Dear Tyler,

Thank you for your help. My sincere apologies for the delay with the appraisal.

The presented object appears to be a Springfield flintlock rifle. The lockplate is stamped by Springfield US and dated 1807 and has a nut wood stock.
Comparable objects were recently offered and sold on the international auction market. 
This piece is in medium condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 800 to 1.500 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
