Re: wanted plans for simple single engine steam en

Semple Engine Company sells completed steam engines and steam engine kits. They also will sell separately only the prints and instructions for their steam engines.

For example, plans and instructions for their 3" x 4" 5 hp single cost $12.74.

They do not have a web site. In fact, their literature doesn't even have a phone number on it. But here's their address so that you can request their information:

Semple Engine Company P. O. Box 6805 St. Louis, MO 63144

I hope this helps you.
