Help to ID engine

[Modhydro]

A friend of my father-in-law was going to pitch this in the dumpster while cleaning out the basement of his business and then remembered that I mess with this sort of thing.

After a lucky save I'm trying to ID the engine. It has a 7.6" diameter flywheel, bore of 1.4" and 2" stroke.

Any help is greatly appreciated as all searches I've done have come up empty.


Thanks

Steve
