Our Assessment: The M1 Carbine was developed and produced after WWII started. Over 6 million were made by a number of U.S. companies to assist with the all out war effort. The M1 Carbine was widely issued to U.S. Military Forces which numbered over 16 million during WWII. The M1 Carbine contributed greatly to U.S. efforts during WWII.
Irwin-Pederson M1 Carbines are RARE. Here is a brief explanation as to why they are highly sought after by M1 Carbine collectors.
Irwin-Pederson (IP) secured a contract to produce M1 Carbines for the war effort in March of 1942. Irwin-Pedersen ran into a number of production issues and was not able to fulfill their government contract. Saginaw S’G’ took over the Irwin-Pedersen facility in April of 1943 and produced M1 Carbines using Irwin-Pedersen and Saginaw S’G’ parts. Irwin-Pedersen had assembled only 3,542 guns at the time, none of which were accepted by the government. Any completed Irwin-Pederson rifles were most likely reassembled and reinspected by Saginaw S’G’ after they took over the contract.
There are 2 separate Saginaw Gear manufacturers. Both were Divisions of General Motors but were located in different cities. Saginaw Carbines made in the original Saginaw, Michigan factory are marked “S.G.” or “SG”. Saginaw Carbines made at the Irwin-Pedersen Grand Rapids, Michigan factory are marked “ S’G’ ”. Saginaw marked the Grand Rapids factory M1 Carbines S’G’ to differentiate them from the ones produced at the original Saginaw plant.

This Irwin-Pedersen M1 Carbine uses all original parts that were made prior to Saginaw S’G’ taking over. Most of the parts have distinctive Irwin-Pedersen markings on them. It appears that the buttplate marking has been lost to surface erosion. Irwin-Pedersen is one of only 3 manufacturers who marked their buttplates. The Underwood barrel is original. Irwin-Pedersen did not produce barrels. Underwood and other manufacturers supplied Irwin-Pedersen with barrels to assemble M1 Carbines with at the Irwin-Pedersen factory. This rare Irwin-Pedersen M1 Carbine in Very Good Plus condition. It has seen some use but most of the markings are in great shape. This Irwin-Pedersen M1 Carbine will stand out in any collection. Good luck.
