"The Colt was obviously an American side arm"
If you're talking about a WWII era, M1911, .45 Colt, then you have quite a treasure on your hands. If it's in the 90% or better for condition, then I'm guessing that it's worth four figures at least. I've seen them run anywhere from $1200-2400 in online sales.
The rest of them? Good luck!
