Design

This is literally a miniature No.9. Almost every feature is replicated in small size. Other than the number of bolts used to secure each part the only differences are; a combined Eccentric Strap and Rod, no Valve Rod Guide. The valve chest cover has a circular recess cast in the front, originally designed to break up the plain surface, later engines had the S logo cast into it.


Evolution

The No.10 H had a single evolution from the originalm single sided croshead guide to the tubular style. This allowed the engine to be set to run in either direction without excess strain. Mounting the soleplate is however trickier to mount for machining.

C. H. P. writes :—
"I have had the No.10v Engine for 5 years, and it has run on an average five nights a week, six hours a night. I am running the engine in our town on Saturday night for the Hospital, so I want it to be at its best, and show them what the Stuart No. 10 can do, and the workmanship of your parts.
