Scotch crank steam pump - stock code 3709

A beautifully-made small steam pump, fabricated from stock material and finished to a high standard. The steam cylinder above drives a pumping cylinder below via a Scotch crank - the heavy flywheel gives an altogether more harmonious action than the flywheel-less Worthington types which tend to rattle away like typewriters.

Base 5 x 5 1/2 inches
Flywheel 3 1/2 inch diameter
Bore est. 3/4 inch
Stroke 1 inch
