New to me M1A1

[bcon]

I just purchased from my Father-in-law a M1A1 Carbine Serial # 203xxx

He has had this in his safe since the late 50's or so. I also have a handbook that looks pretty aged. The cover says TB23-7-1 / restricted / ordnance Field service technical bulletin no. 23-7-1 / Carbine, Cal. .30, M1 dated march,17 1942

I know there are a lot of things that have to be done to prove that this is orig. It does not have a bayonet mount, and the rear sight is an "L" shaped peep sight...not sure if this makes sense, but by flipping it one way or the other, it has a diff. height.

Is an inland / the butt plate of the folding stock has the number 257614 and then a circle with several lines bisecting it (into 6 small "pie" pieces) followed by the #3

there appears to be a faint Capital "P" inside of a circle on the back side of the receiver (on the wood) and some mark on the bottom of the "pistol grip" which is mostly obscured by the connector to the folding stock. Looks like an IO or 10

There is also a mark on the strap swivel UI

Glad to have found the site! Am already thinking I need to find a strap and maybe a Garand!
