I sold my 1945 Colt US Army 1911A1 .45 on this site over a year ago for $1,100.00. It was in excellent shape and had all of its original hand finished parts except for the barrel, which I understand was updated by the US military in the sixties.
I had bought it about ten years ago from a local dealer for $250.00 and, in my youthful ignorance, didn't think too much of it - just an old army gun that was very tight and looked like it hadn't ever really been shot. I shot it once in a while, very rarely, but a couple of years ago, when I learned what it was worth in that kind of shape, I stopped shooting it in order to avoid breaking any of the parts.
I sold the gun and parlayed my profit towards a very nice Dlask custom 1911 .45 "shooter", with all the stuff that I wanted on it (see pic below).
The old Colt went to a guy who was a very serious collector who wanted one from 1945 (he already had others from other years). He was a very happy customer.
For your pricing info, I started offering the gun at a higher price, and progressively lowered it. I had no interest in it until I posted it for $1,100.00 before going to bed. The next day I had FIVE emails from separate buyers who firmly wanted it. I sold to the guy who had responded first.
