Single shot, powder, muzzle loaded, personalized rifle. Approximately 4 ft long. Found in upstate New York near Fort William Henry and Fort Ticonderoga.
Thank you for the additional images and your patience.
The presented object appears to be a percussion lock rifle that was produced for the US military and personalized with decoration in later usage. There are no hallmarks of stamps visible to identify the maker of this rifle. The lock is stamped with the US which indicated that this rifle was produced in the middle of the 19th century for usage in the US military. The short stock is comparable to the 1863 US Civil War Springfield Rifle but this rifle differences in the part and fixing of the lock. This could be a combination of older and different parts. The stock could be older than the percussion lock.
This piece is in medium condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 300 to 600 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,
