Being you don't have a serial number,are there any other markings on it?
single arm action tube?
old style mag tube?
old style bolt?
old style safety?
old style recoil pad?
any pics?
Some of these might help you ID your 500?????
Thank you sir. I will investigate. I’m going to see it Wednesday. Just want to have all my ducks in a row. Seller is claiming it’s a 1961 and i just want to verify that.
He says it just says 500a and course the adress O.F. Mossberg. More I think of it, it might be a 1965+. Because the wood forend although is single action bar it has checkering on the bottom. Don’t think checkering was until after 65’?
