Part-built Stuart No.9 mill engine - stock code 12800

An early stage Stuart No.9 mill engine, with machined cylinder, crosshead and connecting rod assembly mounted on the bedplate.

Complete with drawings and various loose castings as shown (including the optional governor), although missing the crankshaft - we suspect most these days would fabricate from stock material rather than turn from a casting.

Includes free UK shipping.
