A few years ago, I saw Dave Richard's O-S steam engine running his line-shaft-powered machine shop and decided that I had to model this engine.
See 2:26 for Dave's O-S engine.

Just make some castings and sell me one and quit whining. Have you got an idea how many HP this engine is? What is the weight?The only difference I can see between the Isbell-Porter engine and the O-S engine is that the O-S engines had "O-S" cast into the top of the engine base, as can be seen in this photo.
I am not sure who's engine this is (no my photo).
I have only been able to find three of these type engines; 1. the photo attached, 2. the Isbell-Porter at the New England Wireless & Steam Museum, and 3. Dave Richard's O-S.
Dave Richard's engine appears to use a fabricated flywheel, so perhaps the original flywheel was lost.
You can see the 'Trade "O&S" Mark' cast into the top of the base on this engine.
Not my photo.
