On offer is a working Stuart S50 mill type steam engine mounted on a base with a steam boilerplant, I inherited this around 30yrs ago and have only just now cleaned off the storage grime and fired it up to see if it works. Doing some research on the internet it looks like this Stuart is not the later type with cast iron cylinder but the intermediate type with bronze/gunmetal castings. Fitted to the engine is a displacement lubricator. The boiler is a simple pot type built of heavy gauge brass tube around 120mm in diam.
Fitted with a safety valve, water gauge, pressure gauge and stop cock. There is no boiler certificate so this cannot be steamed in public. The burner is the vapourising spirit type where metho is heated to boiling with a simple wick type burner and the vapour is then burnt in two burners as can be seen in the pics. I first tried the engine with compressed air it runs ok (slowly) from around 10psi and then tried the steam power plant with vapourising burner, a video can be seen of this working here.
