This strange engine part doesn't look like it fits in a steam pump, much less anything else you've seen. Perhaps K. Lee Smallfry might know something about it.

This is somethin' real special. Difficulty to say where it's from--like it just fell out of the sky. I'm gonna hold on to this and pay you for your troubles.
Between you and me though, I think it's best if we didn't mention this to anyone.
