Because ALMOST all GI 1911A1's have been re-worked over the years since WW II the price of an unmolested example can be very high, like 2-3 G's and up. It takes a trained eye and knowledge of how and when certain markings, like serial numbers, etc. were applied during manufacture. Late war (1945) unissued/un-used guns with original finish and parts are out there. buyer beware.
