Engine details include a single inverted vertical all-brass cylinder of approximately 3/4" bore x 2" stroke, the engine side-mounted, set on angle, to vertical boiler with a 1 1/4" diameter brass cylinder side-mounted valve chest with removable threaded cover revealing a crankshaft arm driven piston D-valve adjustable cylinder and chest packing glands, well-detailed all-brass hand main throttle valve with piping to boiler, the engine with double tapered steel connecting rod with strapped bearing ends, each with internal adjustable brass bearing surface, single 2" diameter crankshaft disc, twin crankshaft main bearings, each with removable brass bearing cap, each with provision for oiling, single 6" diameter heavy cast 4-curvilinear spoke flywheel with a 5/8" polished face, 3" diameter flat belt pulley with a 1" raised center face. Other fine engine details include: an all-brass crankshaft-driven eccentric strap and pump rod to a base-mounted positive displacement boiler feed pump, complete with twin check-valves, intake piping and output piping with fittings to boiler.
