A Stuart Sun, mounted on the maker’s extended iron
bedplate allowing it to be coupled to a pump or dynamo. It ran well when it
arrived, although with a tight spot when turned over by hand. Remarkable, as the
reason is a twisted connecting rod – they are in bronze so it could be
carefully detached from the cast iron piston and straightened out.
Flywheel 1 ¾ inch diameter
Overall length 6 inches
