Copper alloy gear wheel. A cast discoid plate with twelve spirally radiating points, of which at least two are bent out of their true positions. A central drilled hole of diameter 6.7mm was presumably for a spindle or axle. From machinery, possibly hand-operated: that class of seed drills which occasionally provides detached spoons might be an example of the type of agricultural machinery from which this object may come. Suggested date: Post-Medieval, 1750-1900.
