Gents - I'm a bit out of my comfort zone on this. A friend has a USGI National Match 1911A1 for sale and I'm not sure what to offer for it. The frame is a 1945 Ithaca with the correct marks and checkering on the front strap and the slide is a NM Colt. I don't think the barrel and bushing match the frame though (the guy is checking it tonight - they are supposed to be electro-pencilled the last 4 of the serial # on some of the parts) although they are National Match marked. If it's not all correct what would it be worth? I'm thinking not much than a standard 1911A1. Thoughts?
