Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

By the way....I think yours has a double-action engine, although the
steam pipe only serves the front end.  My engine is a single-action and
I've had both.  Mine needs steam oil so it is good that I can remove
the piston/rod and coat the piston and cylinder for the best runs.  It
also has the band-heater solution.
