Dear Geisa,

Thank you for contacting Mearto with your appraisal inquiry.

Sadly regarding technical problems, the images and messages were not displayed. I apologize for the delay of the appraisal.

The presented object appears to be a non-functional reproduction of a gun of the 18th century. This piece was made for decorative purposes in the 20th century. The technical parts, the surface, and the decoration are not congruent with historical weapons of this time.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 0 to 20 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,
Georg
