[SEL] Venn-Severin engine

[Bob W7AVK]

Peter - Can't say for sure, you maybe correct.  Notice in the same photo 
the large old fashion blow torch mounted in such a way to heat the area 
of iron around the cylinder head top.

I live less than 100 miles from Medical Lake, WA. USA and didn't know of 
the engine but the State Hospital has been there for years.
