Wheel-lock spanner

Wheel-lock key, having a double-ended key cylinder of octagonal section, engraved with foliage, and set at right angles to the stem. Stem of hexagonal section with deeply-cut mouldings, similarly engraved. Near the centre is fixed a swivel for suspension, this being the point of balance. The end of the stem is flattened and broadens to an oval, which is pierced with intricate foliage and scrolls. It terminates in a straight edge forming a screw-driver. The spanner heads are of two different sizes (see note under A1309).

Probably German, mid 17th century.

A similar key is in the Victoria and Albert Museum (no. M 502-1927).
