Found this Ad on craigslist for steam engine and boiler. Pictures of engine, but not boiler.
Curious if anyone has any info about it.

Looks like a small (few horsepower) horizontal stationary engine, very complete, and high quality. It comes with a good inertial governor too. A real gem for a collector, although not a marine engine.
