1943 Irwin Pedersen-Saginaw Gear S'G' M1 Carbine

Here is a M1 carbine made by Irwin Pedersen-Saginaw Gear and has the S'G' mark it. Metal is well used and has some pitting on it. Stock has foreign writing on it and mag and top wood appear to be newer replacements. Old and hard to read, small import mark on the left of the receiver. 1943 barrel and decent/good rifling.
