Made between 1848 and 1860 and is a 41 caliber with silver trim and the P Star burst on the left breech flat. The mechanical function is very good and tight with a very good bore. The wood is very nice and all of the markings are sharp and crisp. The overall length is 5 1/2” long and 3 3/8” high and the finial pattern is like the #6 pattern in Flayderman’s book. No visible serial number. The only fault I find is a small piece of the hammer skirt is missing, other than that this is very nice Henry Deringer pistol.
