1942 m1a1 carbine

So I found this M1A1 carbine. Barrel date 08-1942, serial number 48404.  Stock and inland carbine are consitant with very early inland. My books indicate this serial number is to early. I have found posts indicating that production started at around 30,000. Nra says production at 42000. Another forum post indicates documented possible test rifles starting at 36000. 

thanks. Guys.

That is one sweet M1a1.

I believe this one to be a correct extremely early one. Going through books and parts list everything is correct for a really early inland down to serrated mag catch, springed pin, cross serrated push safety, single slide dismount cut on early receiver.  Only part I found replaced was the type 1 firing pin. It had a type 3 SG.

Thanks for the picts!

Thanks

FWIW, my M1A1 serial #247094 had the short screw in it, unfortunately the wood inside the grip was stripped out where the short threads of that screw were, handgrip was very loose and would not tighten. Ended up replacing the short screw with the longer screw.
