Dear Nathan,

Thank you for the additional images and my sincere apologies for the delay with the appraisal.

The presented object appears to be a replica of a Harpers Ferry 1807 flintlock system pistol made by Pedersoli in Italy. Pedersoli is a known producer of quality flintlock and percussion lock replica guns and rifles. This piece was made in the 20th century.
This piece is in medium condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 80 to 200 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
