The box and cartridges are in very good condition, the cartridges showing copper casings with no headstamps except for one (1) that has “U” on it. These cartridges have pointed bullet and are shorter than a .44 Henry cartridge. They were specifically for pistold like the Connecticut Arms, Hammond Bull Dog and other period “Bull Dog” pistols chambered in .44 Rimfire. They could also be used in the Colt Open Top revolver and early Colt SAA’s chambered for .44 rimfire.
