Recognize this steam engine model?

[myrickman]

I am restoring this engine for an old friend of mine- is it a model or just a small engine?. In the process of having 2 flywheels cast (missing) from the pattern shown and making an eccentric to actuate the steam valve. Does anyone recognize the model? I am guessing he has had it for 30-40 years.... Would like to see how it should look. Lots of the parts were fabricated from bar stock like the crank journals and crosshead.

I know it's not one, but there are certain similarities to a Stuart Turner No.9

Have a look at these pics:

The steam chest on your model is reversed to this one. Note the unpainted pad - where you have a valve lever.

Unfortunately, I can't claim to be the builder of this beautiful engine.

Could that possibly be a Stuart #8? The flywheels are not of that maker but the base etc. sure could be one.

Stuart model #9.... just sold mine a few weeks ago.

Note that the No.9 has only 4 hold down bolts on the bed plate, Myrickman's has 6.
The crosshead and slide bars are of a different design to the No.9.
The valve gear is different to the No.9.

The base casting certainly does have a lot of resemblances to the No.9.

I suppose the original builder could have modified the design somewhat, but I think not. I believe Bearcar1's guess is the right one.

Forgot to add that this model has a 2" bore- all the Stuarts appear to be smaller bore. The base + cylinder is ~16" from tip-to-tip.

Had some nice CI flywheels cast and turned. Stripped the castings and painted them with faded polyurethane- here is the end result. Runs nice on compressed air. The base is old mahogany.

Its come out very nicely, myrickman.
Well worth the effort you have put into it. The CI flywheels made a big improvement.

Say, 'Rickman, were you ever able to positively identify what engine that is? I still think it is a Stuart #8 or 8A, the predecessor to the popular #9.
