I have a Colt New Model Police revolver. Slick trigger. It is a .36 cal percussion cap revolver from the mid 1800’s. All matching SN’s. Never fired a round from it myself.
My Brother, the same guy who had the Colt New Service dug up a Colt 1851 Navy from the ground in his Wife’s parents barn.
As you might guess it was pretty rough. With the help of Dixie Gun Works, he actually restored it to working order. I am not sure how many original parts it had but the frame and cylinder are original. I guess his Son has it now.
