Side Notes:
- Inland was the forerunner for all to follow. Other contractors were gearing up to manufacture the Carbine and Inland provided most of the tooling and production procedures that would enable the others to begin full production.
- Any Inland Receiver with a 'X' after the serial number means that serial number was used by Winchester, its a duplicate so to make it different Inland put an 'X' after the serial number.
-All matching vs how it left the factory:
****** There is a difference between an all matching carbine and how it left the factory, a lot of M1 Carbine contractors shipped parts to other Contractors. Just because its all matching doesn't necessary mean that is how it left the factory. So don't get super disappointing if your Carbine is not all matching, its possible its exactly how it was when it left the factory!!! An example say Underwood was low on sears, Inland would ship some Sears to them. Sometimes marked or unmarked. Here is some known shipments to Inland, how ever there could be more shipments that occurred that are unknown but this is a good reference. (most parts were shipped together in groups, magazine catches with sears, etc)
(Organized by year. 1942 - 1944)
-Underwood shipped approximately 16,000 Firing pins to Inland in 1942.
-Winchester shipped approximately 1,200 firing pins to Inland in 1942.
-Rock-Ola Shipped approximately 10,000 sears to Inland in 1943.
-Underwood shipped approximately 4,000 Rear (Flip sights) to Inland in 1943.

Us Carbine Serial Numbers

-Winchester shipped approximately 4,000 hammers to Inland in 1943.
-National Postal Meter shipped approximately 25,000 Rear (Flip sights) to Inland in 1944.
-National Postal Meter shipped approximately 1,000 Rear Sight Leafs to Inland in 1944.
Example: You have an all matching Inland except hammer that's marked 'W' for Winchester, there is a good chance it left the factory just like that!!!

--Some history of Inland:
'The Inland Manufacturing Division of General Motors was organized in 1922 for the manufacturing of wood wrapped steering wheels. The division used the buildings and technology of the defunct Dayton Wright Airplane Company. The division was unique as the only division created within the corporation, not acquired by purchase.
By 1924, the wooden steering wheel had been replaced with the hard rubber steering wheel and the division gradually transformed from a wood working operation to a rubber processing operation.
A wartime shortage of men and women to fill jobs led to the enactment of a “buddy” shift. The first business in Dayton to adopt the new buddy shift was Inland Manufacturing. In February 1943, Inland hired a number of high school boys to work at Inland after school until 7 p.m., at which time men and women who had full time jobs during the day would take over and work until 10 p.m.
Inland Division of General Motors was one of nine contractor-established manufacturing facilities that tooled up and turned out M-1 carbines during WWII, a five-pound rifle considered the nation’s best ordnance effort of the war. By the end of the war, Inland had produced over two and a half million carbines. Inland also produced a one-pound pistol called the “Little Monster”, which had been designed to be airdropped to resistance fighters in Europe.
During the war Inland also made tank tracks for America’s leading tank manufacturers, as well as Great Britain’s. At war’s end almost 20 million tank shoes of various sizes were fabricated by Inland. The diesel tank clutch was another product developed by Inland. Inland also made gun sights and shoulder rests for the rapid firing 20mm anti-aircraft gun. Helmet liners were produced in great quantities by Inland. Fire extinguisher horns used on United States Naval ships were in short supply and insufficient strength. Within 60 days Inland was mass-producing a new and improved horn. Inland aircraft hose, steering wheels, gaskets, sleeves, bushings and countless other small parts were produced for the war effort.
After the war, Inland applied its experience to mass produce plastic and rubber steering wheels, clutches, motor mounts, running boards, gravel shields, brake linings, weather strips, refrigerator door seals, defroster hose, small plastic parts, radio cabinets and many other products. Inland practically took over the metal ice tray business producing trays for almost all the large electric refrigerator companies.
By the 1950’s, Inland was making brake linings, bumpers, turn signals and a host of other automotive products. By 1982, it also was turning out fiberglass suspension springs for the Chevrolet Corvette.
In 1989, the Inland division was merged with Fisher Guide to form Inland Fisher Guide. That was later grouped with GM’s other components divisions to form the Automotive Components Group (ACG).
In 1995, ACG was renamed Delphi Automotive Systems and spun off from GM in 1999.'

Some people estimate a carbine's date of manufacture by adding the quantities manufactured month to month to the assigned serial number blocks. This is not an accurate means of estimating the date the carbine was finally assembled or when it passed its final inspection. Serial number blocks were assigned by the Ordnance Department on an as needed basis, generally in response to the awarding of a contract to a given manufacturer. Think of each serial number block as a separate contract. Contracts had a completion date but there was no requirement for completing one contract before starting another. There was no requirement as to using the serial numbers in order. A few manufacturers used some serial number blocks out of order. Some of these blocks were split up and used before or after other blocks. Some manufacturers used more than one block in the same time frame. A few of the manufacturers used subcontractors to manufacture their receivers. One manufacturer separated out smaller blocks of serial numbers for use by subcontractors who would use these serial numbers concurrent to receivers being made by the prime contractor and/or other subcontractors assigned lower or higher serial number blocks. The serial number was placed on the carbine receiver during the manufacturing process of the receiver, not when the carbine was finally assembled. The decision for which receivers would be used for the U.S. Carbine Models M1 or M1A1, and some of the M2's, were made well after the receiver was completed as all of these models used the same receiver. Serial numbered receivers that failed to pass inspection were set aside as rejects if the defect(s) could not be brought up to minimum standards. As solutions to old problems were learned, some of the same receivers were brought back online and completed (i.e. Inland receivers initially rejected because of an off spec deep hole drilled for the recoil spring and guide, later recovered and altered to use a detachable main spring housing). If a receiver was scrapped and not used, its serial number may or may not have been reused. No documentation from Ordnance, or any of the prime contractors, has been found that indicates the date and serial number of carbines as they were assembled or when they passed final inspection. Given the high volume of production, receivers were generally assembled as part of a carbine within a few months after the receiver was serial numbered. Barrels were a critical component in the production lines. If inventory ran out it could shut down production. Four of the prime contractors did not have the ability to manufacture barrels. The ebb and flow of mass production created parts surpluses and shortages for all the prime contractors, barrels included. Shortages were common until Ordnance arranged for additional barrel manufacturers. During the first half of production the barrels were often mounted on a receiver within 1-2 months of when the barrel was made. If a receiver has its original barrel and the barrel includes a date, it may provide a general idea of when the barrel was attached to the receiver. As time goes on more and more carbines are having parts replaced. Parts wear out, carbines are disassembled for the sale of the parts individually. Carbines have been, and still are, rebuilt from spare parts. Many people have reconstructed many carbines with what they believe should have been on the carbine when it left the factory.

Notice

Tables C - F

Documents found in the past have identified several prime contractors who assigned subsets of their serial numbers to their subcontractor(s). Data collected over the years has sometimes conflicted with the information in these documents. There are a variety of reasons things may have been changed or simply ignored. Rather than assume the documents were followed to the letter, the serial numbers in tables C-F are presented with the lowest and highest reported to date. We would like to encourage you to share information you may have that will help reconstruct what was actually done versus planned. If you choose to do so please contact us using the forum.

TABLE D Leftover Receivers used by Winchester

Underwood had receivers in various stages of completion left over when their contract ended. These receivers were purchased by Winchester. What followed was not always consistent and sometimes varied. The information that follows has been reconstructed from the data collected so far. It is not unusual to find a receiver that doesn't fit these criteria. The focus at Winchester was meeting production quotas during a time of high demand.

- Underwood receivers that had not yet been hardened: Winchester removed the Underwood name and serial number, then replaced them with the Winchester name and serial number.

- Receivers that retained the Underwood name: Winchester sometimes lined out the Underwood name, sometimes not.

Winchester added the letters W A or A W to the bevel of the receiver. - If the receiver had an Underwood subcontractor code, the subtractor code was left in place between the W A or A W. - One or both of the letters of the W A or A W code may be difficult to see. Some have been reported with only one of the two letters or in combination with an Underwood subcontractor code. - The significance of the letter A is unclear.

Ordnance required the name of the prime contractor to be defaced by a single narrow horizontal line. The
identification mark of the receiving facility was to be added at the rear of the serial number.

TABLE F Serial Numbers Duplicated (including use of X Suffix)

Prime contractors and/or subcontractors sometimes ran over their assigned serial number block and into a block assigned to
another prime contractor and/or subcontractor, creating duplicate serial numbers. Ordnance dealt with this by directing
an X be added after the serial number of the receiver that exceeded the assigned block if duplicates were found.

There is insufficient data to determine if every serial number between the lows and highs was duplicated or if it was random.
It is assumed some were sequential but possibly not all. More data submissions are needed to help determine any patterns.

TABLE G Irwin-Pedersen, Grand Rapids, & Saginaw

None of the carbines produced by Irwin-Pedersen (IP) were accepted by Ordnance. Saginaw Steering Gear in nearby Saginaw, MI was already engaged in the preparation for the manufacture of carbines along with providing subcontracted receivers for Inland. The Irwin-Pedersen contracts were terminated by Ordnance. An Ordnance supplement to the Saginaw Steering Gear (SG) contract turned over carbine production at the Grand Rapids facility (S'G') to Saginaw Steering Gear. Irwin-Pedersen Numbers Reassigned to Saginaw at Grand Rapids Grand Rapids manufactured their own receivers as well as using viable IP marked and serialized receivers they had acquired in the takeover. Serial numbers IP had not yet used were used by S'G'. As were serial numbers from IP receivers that were scrapped

Saginaw Receivers with SG Subcontractor Markings Receivers produced at the Saginaw plant under subcontract to Inland initially had the SI receiver code on the left side of the receiver below the wood line. The receiver code was soon changed to SG. Receivers with the SG receiver code were intended for use by Inland though they were also used by Saginaw. The serial numbers and manufacturer names identify who actually used the receiver.

The data on these receivers, serial numbers, and prime contractor names is an ongoing research project that needs your help. Serial Number Range S/N Block Assigned to 3,541,000 3,651,519 Saginaw Saginaw receivers with Saginaw serial numbers have been reported with S'G' markings. At least one document has been found that indicates Saginaw received Ordnance authorization to sent an unknown quantity of receivers to Grand Rapids. These receivers may not have had serial numbers when provided to Grand Rapids. The Grand Rapids facility stopped carbine production on 01 Jan 1944 but continued to make receivers and trigger housings which were sent to the Saginaw Plant for assembly.

TABLE H Inland Manufacturing Engineering & Presentation Gift Serial Numbers (not government issue)

Letter prefixes X through XD were initially allocated by Inland for carbines intended for internal use only. The letters were followed by numbers (i.e. XA27, XA62, XD14). XA through XD was assigned for use by their Engineering Section on carbines built for testing and evaluation by their engineers. The quantity of carbines used by their Engineering Section varied so the numbers with each prefix also varied. Inland later decided to present carbines as gifts to Inland employees, subcontractors, suppliers, members of the military or government, and others to show appreciation for their assistance and cooperation with Inlands war effort. The serial numbers allocated to these carbines were as follows.

Start Serial Number End Serial Number X1 X100 XA1 XA100 XB1 XB100* XC1 XC100 XD1 XD100 XE1 XE100 XF1 XF100 XG1 XG100 * XB271 is a documented exception

This resulted in an unknown number of 'presentation' carbines possibly having the same serial number as the earlier Engineering carbines. The carbines used for this purpose were not from inventory submitted to or accepted by the government. Many were constructed using whatever parts were available. Examples being outdated parts and prototype parts that had accumulated throughout the various departments within Inland over the years of production. This included a few of the previous Engineering carbines no longer needed. Carbines that have one of these serial numbers may be an Engineering prototype, a 'presentation' carbine, or both. They are a specialty that requires each be assessed individually to determine its historical significance. They should not be altered or fired. Doing so may alter their historical value. Assistance Available Should you own one of these carbines we may have additional information on your carbine that is beyond the scope of this website.

TABLE I Carbines with a Serial Number above 8 million

Post WWII, the Office of the Chief of Ordnance (OCO) assigned replacement numbers to armories, arsenals, and depots for carbines having damaged or obliterated serial numbers. Numbers were issued sequentially, beginning where Ordnance had left off with serial number blocks assigned during WWII. The letter X preceding the serial number designated it as a replacement. The new serial number was hand stamped on top of the receiver behind the rear sight, in the vicinity of the prior serial number.
