1937 Krieghoff Suhl luger
 

Mint conditon luger from 1937 ser 8577 looking to see a value for this pistol I rescued this from my grandfathers attic in a cardboard box with absolutely no rust damage etc. after being up there for 30 + years. I have one magazine.

Let me be the first to congratulate you on your rescue (and welcome you to the forum!:)), and also the first to advise you that it is very (repeat, very) difficult to evaluate a gun without photos...preferably a bunch of them. There are many factors that can affect value and there are many folks on this forum that would be delighted to help you if they had something to work with.
