Old model mill engine, probably dating from late nineteenth century. Constructed entirelt in brass with fish-bellied connecting rod, overhung crank and slide bar crosshead. 1 inch bore, 1 1/2 stroke. The engine is nicely made with wood-lagged cylinder and an interesting bell-crank driven boiler feed pump. Runs very well at low pressure (indeed, on lung power alone!).
Length 13 inches
Flywheel 6 inch diameter
