For smithery, H. M. Dockyard Woolwich. Forge engine, working tilt hammers. According to Engine Order Book No. 8, the engine was actually made in 1811, but appropriated for the Dockyard in 1815. The Catalogue of Old Engines lists this engine under Dockyard as well as crank engines, and under the Dockyard entry [p. 150] it erroneously states that the drawings are in Portfolio 663.
Note that on the plan copied from Dupin in 1833 (see below) this engine is marked as a 24 horse engine. The engine was later sold and erected near Sittingbourne in Kent.
