is the case with the 10H, simply sold as a "factory made" engine by a
secondary seller. I assume that meant it was one of the finished
engines Stuart sold, but aside from the fine pinstripping on the
engine, I have no way to verify it's parentage.
The 10H is the horizontal version of the 10V that follows this section. The 10H spans 6 inches in length, and has the same 3 inch flywheel and 3/4 inch bore and stroke as the 10V.
Stuart notes the 10H will run from 200 rpms to 2000 rpms making it well suited for driving other models such as their Dynamo or Oil Field Pump (sure wish I had those!!)
it to say this little engine runs beautifully on live steam from a 3"
Jensen boiler or compressed air.
example and other Stuarts are in a different class than the rest of my
collection...not so much from a size standpoint, but a precision
machined engine like this really showcases an individual's work and is
closer in reality to the real engines these are based on. Lovely stuff.
