Mystery machine

[Roger Taylor]

I picked up this little mechanical device at a flea market. it seems to have missing parts. The head or cover is missing from the small .5"lD cylinder visible from the top. Steam engine, 2 stage air compressor. Thanks, Roger-clueless IC guy

Add air thru the elbow and flick the flywheel......should run......the exhaust is open at the top & the intake passage is internal....neat engine
