Dear Robert, Thank you for contacting Mearto with your appraisal inquiry. The presented object appears to be a Parker Bros hammerless side-by-side double-barrel 12 gauge shotgun. It has the serial number #71787 and the lockplate is decorated with engraved decor. It is probably a D-grade product and has twisted barrels. Comparable objects were recently offered and sold on the international auction market. This piece is in good condition and there is no serious damage visible in the images provided. A fair market estimation would be between 500 to 1000 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
