I wish I could help everyone, but with over 6 million U.S. Carbines and almost 1 million post war commercial carbines one person can't handle all the requests for assistance. However, there are a number of resources available that can answer any question you might have, including groups of knowledgeable collectors and shooters on discussion forums. The internet is ripe with experts on almost every topic, so you would be wise to get opinions from more than just one person.

Overview

Between June 1942 and August 1945 ten primary U.S. contractors manufactured over 6 million U.S. .30 Caliber Model M1, M1A1, M2, and T3 Carbines. During World War II these carbines were issued to U.S. soldiers in every theater of war around the world. M1 Carbines were supplied to a number of Allies via the Lend/Lease Program during WWII. Carbines were smuggled into, or parachuted to, resistance groups in a number of different countries during the war.

After the end of WWII many of the carbines were returned to America, where they were inspected, refurbished, and/or rebuilt to the latest standards. Many of the carbines did not return to America. Instead, they were stockpiled in various countries in case they were needed.

With the onset of the Korean War in 1950, the .30 Caliber Carbines once again served American troops and America's Allies. However, during this war the decision was made to offer the .30 Caliber Carbines as a main battle rifle, a role it was not designed for. It's not surprising the carbines used in Korea received a reputation as totally inadequate. The wrong tool for the job at hand. City fighting at distances of less than 200 yards, the carbines were usually adequate, which would later make them popular with police departments around the world.

Of the over 6 million carbines built, over half were at some point provided or sold to other nations as military assistance (see below). Many of these nations sold part or all of their carbines to other countries around the world.

Since the early 1960's private importers and exporters have acquired a great many of these carbines and sold, traded, or brought them back to the United States, where they were sold to civilian gun owners. Through the Director of Civilian Marksmanship and eventually the Civilian Marksmanship Program, the U.S. Army has provided thousands of carbines for raising funds to support shooting programs across the nation.

The popularity of these carbines has led many to collect them or simply buy one for home protection or recreational shooting. If you are one of these people, or intend on becoming a carbine owner, this page is for you. The information provided here is basic and meant as an aide, introduction, and simple reference material for you to refer to should you so wish.

U.S. Caliber .30 Carbine Models

Models M1 & M1A1

"The only difference between the carbines M1 and M1A1 is the stock. The M1 has a one-piece wooden stock, whereas the M1A1 has a folding metal stock extension and a wooden hand grip."

[TM 9-1276 Cal. .30 Carbines M1, M1A1, M2, M3, U.S. Government Printing Office, 1953, paragraph 5, page 3]


U.S. .30 Caliber Carbine Model M1


U.S. .30 Caliber Carbine Model M1A1


U.S. .30 Caliber Carbine Model M1A1


Model M2

"The carbine M2 is the same as the MI except for differences in design of certain components and the addition of others ..., which permit the M2 to deliver either semiautomatic or full automatic fire."

[TM 9-1276 Cal. .30 Carbines M1, M1A1, M2, M3, U.S. Government Printing Office, 1953, paragraph 5, page 3]


U.S. .30 Caliber Carbine Model M2 with birch stock

The receivers used for the model M2 were the same as the receivers used for the model M1. They are interchangeable. The only difference was the M2 marking instead of M1. On some receivers the 1 or 2 was left blank and hand stamped with the appropriate number when the carbine was finally assembled. The M2 marked receivers, with or without any other parts attached, are legally considered machine guns.


Model M3 (T3)

"The carbine M3 is the same as the M2 except that the rear sight is not included and the top of the receiver is designed to accommodate special sighting equipment (sniperscope) issued by the Corps of Engineers. Information on the sniperscope may be found in TM 5-934l."
[TM 9-1276 Cal. .30 Carbines M1, M1A1, M2, M3, U.S. Government Printing Office, 1953, paragraph 5, pages 3 & 4]

T3 carbines were manufactured only by Inland and Winchester. The serial numbers are four digits and not related to the blocks of serial numbers issued to the various manufacturers by U.S. Army Ordnance.

    "Procurement and Supply" by Thompson and Mayo
    as stating a total of 6,117,827 carbines were manufactured."

A Small Footnote

"Carbine Williams"

Established
May 1952
Hollywood, California

David Marshall Williams has been erroneously credited with designing the .30 Caliber Carbine. Williams designed the short stroke gas piston which was a significant contribution, but the carbine was actually designed by other employees at Winchester. Williams had been hired by Winchester and given the opportunity and latitude to come up with his own design, which he failed to do within the time allotted to meet U.S. Ordnance deadlines for prototype submission. A second team at Winchester, working concurrently and separately from Williams, produced the design adopted by U.S. Ordnance.

During his short tenure at Winchester, Williams repeatedly created conflicts with fellow employees that ultimately led to his dismissal. In May 1952, MGM Studios released the movie "Carbine Williams" starring Jimmy Stewart as David Marshall Williams. The movie portrayed Williams as the inventor of the U.S. M1 Carbine. Thereafter Williams became known as "Carbine Williams".

The North Carolina Museum of History in downtown Raleigh, NC, relocated Williams' personal workshop to their museum, where it was reconstructed with minute detail and opened as an exhibit. The workshop exhibit is located behind a see through partition that prevents close examination. The South Carolina Military Museum in Columbia, SC, includes an exhibit of some of Williams inventions and over thirty four of his personal collection of .30 Caliber Carbines. Interestingly, these include a number of post war carbines manufactured by commercial companies.

Producer Michael Mann once told me movies are not about truth or reality, they're about entertainment. A truthful and realistic perspective from a man who has been fairly successful in the entertainment industry. Unfortunately the human mind sometimes has difficulty separating truth from entertainment. Those who deserve the credit for design and development of what became the U.S. M1 Carbine are a group of people who worked for Winchester whose names have passed into history. Williams earned only a footnote. Reality was he interfered with the development, some of it intentionally, as much or possibly more than he actually contributed. Everything else aside, he does deserve credit for the short stroke gas piston that enabled others to design and build the carbine.
