Just to be clear, you do know you have "GOLD" there, do you not?
You need to make every effort to get the best quality pictures you can of it and lots of them, inside and out with a very good background setting. Spend time and do it right. BTW don't change a thing on it, keep it stock and clean it carefully. If you can, do a history write up on it with any documentation you can find. You'll be glad you did.
Then post the results here on INGO for all to enjoy.
10mm when you care enough to send the very best.
Didnt they make M1 Carbines too? Nice piece!
