Set of three Perkins tractors, possibly of steel,
Set of three Perkins tractors, possibly of steel, brass and copper, in tube-shaped black leather case, first half 19th century. This set is probably an imitation, as it is not stamped with the Perkins name, and includes three tractors (two round and one flat) rather than two. Tractors bound together with a small removable ring. Identical to A658228 except this object's case is complete.
