Ski in NC, ever work on a reciprocating steam engine ? All the old Navy destroyers had one in each engine room for pumping bilges. We could even rig them up to run off compressed air when the boilers where idle.
Then there's the movie " Sand Pebbles " that was a Skinner Uni-Flow reciprocating engine, never worked on or operated one of those but had to know them from the manuals for promotion exams.
Correction, I just googled up info on the steam engine and found out it was made by Vickers and the engine room scenes where shot in California. The USS San Pablo actual was powered by a Diesel engine for the movie.
