I recently came into possession of a new in the box, unfired, Colt Single Action Army in Colt 45, 4 3/4" barrel, blued, etc. manufactured last year. The cool thing about it is that this Colt has a black powder frame and bullseye ejector rod. I am told it is a custom shop special. I had no idea that Colt even offered these. Does anyone have any idea what it might be worth?
