SUPER RARE Saginaw Hammer Marking ?

[USGI]

I've got an S'G' Carbine made in 1943 with that hammer. The s/n is 1829338. I think the marking is identical to yours, but have seen a marking that's different - not sure if was fake or not. I don't have access to the computer with pics of mine right now, but hope to later today. The CCC website might help narrow down the dates they were used a bit. My "good buddy" Charlie may be able to help out if he's not still out looking for coyotes. - Bob
