- 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.
-NumbersAll 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.
-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.'
