Dear Stephan, Thank you for contacting Mearto with your appraisal inquiry. The presented object appears to be an Ottoman blunderbuss with a flintlock lock and 2' length. The barrel is decorated with calligraphic etchings and the lock appears to be a European import. The stock is decorated with probably brass inlay work. This piece was made in the late 18th or more probably in the first half of the 19th century. 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 700 to 1400 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
