Winding key

Brass winding key made by Thomas Mercers in 1932 for Gould during the 1931-33 restoration, when Gould oversaw the conversion to key-winding of the H1. The key has a steel pinion built into the end of it, which meshed with a wheel fixed onto the fusee of the timekeeper. This arrangement was all removed during the 1961 restoration.

Key: H:65 W:40 L:230.
