Q. I acquired a revolver that I believe is missing some parts. Can you help me figure out what I’ve got?
A. Unfortunately, I was unable to locate any diagrams or patent drawings of your Gross Arms Pocket Revolver, so I can’t confirm whether yours is missing any parts. I can tell you that the piece was manufactured by the Gross Arms Co. of Tiffin, Ohio (owned by Charles B. and Henry Gross), between 1864 and 1866. Apparently only a few hundred were manufactured. It is chambered for .25 Rimfire, and the rear of the cylinder is removed to allow cartridges to be loaded into the chambers. The ejection of spent cases is accomplished by means of a rod beneath the barrel.
