Similar lines to a Greenly design of the 1920s, a four pillar engine with generous bearing area and robust crankshaft, connecting rod and crosshead assembly. 16 inches high from base to top of cylinder - the flywheel hangs below by an inch or two. Flywheel is 7 inch diameter. Wood-lagging on cylinder in good condition, drain cocks and regulator valve fitted. Would power a small full-size boat.
