Hello, this item is a matched set of percussion-fired firearms, comprising a musket rifle and a pistol, likely mid-to-late 19th century in style. The lock mechanism is of the percussion cap variety, which replaced the flintlock system around the 1830s, and features decorative engraving on both the lock plate and hammer. The craftsmanship appears robust, and although the precise origin is not clear from the images alone, the detailing suggests either European or American reproduction models, possibly for decorative or reenactment purposes.

Given the apparent condition and engraving quality, if these are authentic 19th-century pieces, their value would depend on originality, maker marks, and working condition. However, if they are decorative replicas (which is plausible given the uniform condition and wood finish), their market value is significantly lower. Assuming they are decorative reproductions from the mid-to-late 20th century, the estimated market value for the set would be in the range of $200 to $400 USD.
