Coles C-612 horizontal engine

Set of 15 castings for a Coles C-612 horizontal mill engine, complete with piston rings.

This is a large engine - with 7 inch diameter flywheel, the set of iron and bronze castings weigh in at around 24 pounds.

No drawings, although given the simplicity of a single cylinder engine, it wouldn't be difficult to work out dimensions from the existing parts, bore and stroke measurements.
