Karl's dad has been pretty involved with these engines for a while now. It just so happened that my sister-in-laws ranch used a couple of these back in the day to pump water, etc...
The "show" or whatever you want to call it was at a guy's house a couple of us on here know. A couple of the guys were interesting. I'm hoping karl has met some of them so he can comment.
The 1st one is my brothers. He finished it that day. I'll post more pics if anyone is interested.
