The Colt Deringer was in 41 RF cal with 2-1/2" bbl. This particular gun has a mostly grey coloration with smooth metal. Bbl address and the number 2 on the top of the bbl is very readable. The scroll engraving is quite nice. Some slight pitting on the left hand side. Original rosewood grips are in very nice condition. Deringers are becoming very popular as a collectors item.
