Upshur Vertical gas pumping engine.

[mnay]

I am looking for the plans for the Upshur Vertical gas pumping engine featured in Modeltech March 1999 and April 1999. Anyone know if these are still available? I did not see that particular engine on the Upshur site. It is different from the Upshur vertical single. It iis an open frame and only has one push rod. Any help would be appreciated.

I got some help from one of the RReid on the Model Engine Maker site.
For those interested find the info here.

Hello mnay. The plans you are looking for are included as part of the "Red Farm Engine" plans on the Upshur site. The description on the site, such as it is, doesn't mention it, but that set includes four variants, including the vertical with open frame, pushrod operated exhaust valve, and atmospheric intake valve. I built it myself from those plans a couple of years ago.
