6 ¾” length flattened cow horn with rounded edges and baluster turned spout. Horn base secured with iron pins. The side with brass spanner mount used to wind the lock. “Spanner” is the English term for a wrench universally used to describe these. A wheellock operates by winding the iron wheel against a spring and locking it. The cock, holding an iron pyrite is lowered to the wheel surface and the trigger releases the wheel which rotates against the stone producing the spark. Wheellocks were replaces by flintlocks for military use in the 17th century but carried on into the early 18th century for sporting guns. This example has a lightly scratched 1760 date, evidently from its working life but likely was made about 1700. Age cracks, shrinkage and small damages as expected.
