Dear Richard, Thank you for contacting Mearto with your appraisal inquiry. The presented object appears to be a Balkan area flintlock pistol. It has decorated with mother of pearl and brass inlays and is not stamped or hallmarked lockplate. This is a marriage of differently dated parts as we can see in the older flintlock itself and the late 19th-century brass plate depicting a face on the back of the grip. It was common, especially in the Balkan area to use European parts. Comparable objects were recently offered and sold on the international auction market. This piece is in bad to medium condition and no severe damage is visible in the images provided. A fair market estimation would be between 150 to 300 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, Gregory
