Dear William, Thank you for your help and patience. The presented object appears to be a pinfire revolver. The revolver is not stamped or hallmarked. It is comparable in its design to the Chaineaux pinfire revolver which was in usage around 1850/70. The inside of the handle is stamped by the owner "M.S. Earl". Comparable objects were recently offered and sold on the international auction market. This piece is in good condition and no severe damage is visible in the images provided. A fair market estimation would be between 200 to 400 USD. This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary. With kind regards, George
