Our Assessment: This M1 Carbine has a Saginaw S.G. receiver. Saginaws are known for being made in the same plant as irwin-Pedersen receivers. Iriwn Pedersen was using two blocks of serial numbers at the same time. That confusion was compounded when Saginaw took over the plant. Whatever receivers Saginaw found acceptable were used, and scrapped the remainder. The gaps left by the scrapped Irwin receivers were being filled by Saginaw at some point. In doing so making it practically impossible to date the receivers. Overall a very interesting piece of history to add to a gun owner’s collection. Good luck!
