Here she is, (not complete, but the governor and better plumbing can wait).  I told my wife that this one would not be Stuart green and black, but that is not the case.  The base casting looked nice in its natural state, so at least for not, it will remain bare.

I really like the red stripe on the flywheel.
You have built a very well done model.

Here is an image of my governor prior to setting up the bell cranks and linkage. Unfortunately, small governors aren’t effective at low speeds, so I ran the engine a bit fast to show the function.
Stuart beam engines have 1/32” side to side clearance between the connecting rod bushing and crank pin which makes an annoying clacking sound.  I will be making a new bushing with minimal side play and eventually running a flat belt to bevel gears for the governor.
The governor is based on the Stuart Watts Governor.  The balls and manifold are scaled down by 20%, the arm length increased by .125”, the spring replaced by a weight and the hardware is my own.
I’m fairly happy with it, but it remains a work in progress.

The second picture has it in its home.  It is kept in an antique barrister bookcase to keep it clean.  The environment in a wooden case is nice and stable so oxidation should be minimal through the years.

I made a new connecting rod bushing with minimal side to side clearance and it quieted the engine down.  I also ran it at approximately 4 psi.  I still want to add a regulator and dedicated air line.

I’ve enjoyed the project and adding some personal touches and I am grateful for the encouragement and comments along the way.

Thank you all for the comments.

The bucket is there to collect exhaust oil and to add a little to the engine visually.  I had some leftover thick walled bearing bronze tubing and some Mahogany hanging around, so I made it up.  There is a stepped Brass plug at the bottom and it has a .375” long by .500” diameter protrusion to locate it into the wooden base, (it lifts out for cleaning).  I will ran lines from the drain cocks to the bucket in case I ever decide to run it on steam.
