Springfield M-1. Late January, early February 1942

Hello everyone. First post. I have an early Springfield M-1. Late January, early February 1942. All parts appear to be correct for the make and date, although I haven't had it completely apart to check on those not completely visible. Except, of course for the stock, which is a non-cartouched later stock. I have an SA/GHS stock which was refinished. Although the SA/GHS is still visible, the crossed canons are not (however, with a magnifying glass, great light and tremendous leap of faith. you can make out tiny remnants :).) A couple of questions. 1. If some of the smaller parts are later arsenal replacements, how difficult would it be to obtain correct replacements? 2. There is an SA/GHS stock up for bid on Ebay. How do I determine if it is genuine (I had help getting the stock I currently have)?

Check the "sticky threads" above under Inspection Stamp Quiz by Rick B., you see find both original and fake SA GHS cartouches
