Nick,
I am really glad and excited that you got the red one (and the SIPP of Course, since I know you have been looking for one). I am doubly excited, because I will probably get the chance to see both of these in person some day.
This popped up in my YouTube feed a couple of days ago. Looks like the same engine manufacturer as yours and mine, Although of course mine has a bar stock cylinder rather than the original casting.

This is a short video of my D & M #11 steam engine, running on air. I machined this engine from a set of castings purchased from "D & M Model Engineering" back in the 1980's. According to the catalog description, this engine is a reproduction of a line of steam engines that were available from a Chicago firm in the early 1900's, and long since out of business.
The bore is 1", and the stroke is 1-5/16". The flywheel diameter is 4-1/4". Main engine components are of cast iron, with bronze connecting rod, eccentric rod, and slide valve. The sub-base is cast aluminum. The engine is equipped with a Stuart displacement lubricator, and Stuart globe valve.
