I concur with Paulinski.
Less than a year ago I sold a similar gun, a Colt M1911A1 United States Army .45 from 1945 here on CGN. I believe all of the parts to have been original except for the firing pin and the barrel. I also threw in one correctly marked "C-L" magazine with the gun.
I had no takers until my asking price hit $1100 at which point I received 5 emails from guys wanting to buy at that price. It sold for $1100 to the guy who got the first email in to me. He was a collector who had USGIs from most of the 1940s, but wanted one from 1945.
It's a bummer that we cannot sell these guns to the US where they would pay much more for them. This rule is firm and there is no way around it.
I started my price high and worked my way down.
Good luck!
