Hello Histarch-ers,

I'm inspired by all the industrial machine/process expertise we 
evidently have on this list to make an appeal for help in identifying an 
artifact found this summer at my ca. 1885-1935 dissertation research 
site in Tulare Co., California: It's a cast iron object which looks like 
some sort of cylinder head, and measures very roughly 10" x 6" x 1.5".  
The number on the top view is "6251[?]1-4."

Any ideas on what kind of engine/machine this may be from?

Thanks!
