Wheellock Mechanism for a Pistol

Gold-colored metal mechanism with intricate design on a flat surface. The mechanism is long and thin, with a hole in the middle and various small parts attached. A small lever on the right side. Two separate pieces above the mechanism: a T-shaped piece and a round metal washer with a square hole. The mechanism is labeled as a "Wheellock Mechanism for a Pistol" and attributed to an unknown artist. The background is a beige surface with small brown spots.
