Dear Robert, Thank you for your help and patience. The presented object appears to be a Union Arms & Co double-action black powder revolver. Comparable objects were recently offered and sold on the international auction market. This piece is in medium condition and no severe damage is visible in the images provided. A fair market estimation would be between 500 to 1.000 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
