For smithery, H. M. Dockyard Woolwich. Engine powering tilt hammers, and engine operating blowing cylinders. The Catalogue of Old Engines lists these two engines under Dockyard engines and erroneously states that the drawings are in Portfolio 5/663. The blowing engine is also listed in the Blowing Engines section of the Catalogue, and again the drawings are stated to be in Pf. 663. [Portfolio 5/663 actually contains drawings of a pumping engine with a 36 inch cylinder and 8 ft. stroke.]
