From the Northampton Society stand at the Midlands show in 2019 this Vision Engineering Ltd working model of a York Bolton Mill Engine & Steam Plant, comprises a vertical wood clad boiler connected to a single cylinder horizontal engine with flywheel, regulator and band drive to dynamo, mounted on a wooden base 41.5cm x 39.5cm.

This super model is available as a kit or ready run from The Engineers Emporium. The castings are of brass, all exposed brass is electro-lacquered to stop tarnishing. All hardware is of stainless steel. Painting is stove enamel epoxy.

The Bolton Mill Engine is a horizontal single cylinder slide valve unit. Crankshaft, eccentric and big end bearings are of sealed ball type, concealed to look like plain bearings, but giving long life and zero maintenance. A boiler feed pump and steam lubricator are fitted, together with belt driven dynamo with voltage regulator and lamp standard. Other features are a dummy ball governor and adjustable load damper, together with cylinder and steam chest drain, valves and sump.

The York Steam Plant consists of a feed water storage tank, sludge tank, oil separator and butane holder, which takes a standard internationally available camping butane cylinder, providing about two hours steaming. All elements are mounted on a polished electro-lacquered brass plate and hardwood base.

The boiler is of silver soldered copper construction, fitted with ceramic gas burner with both main and pilot jets, electric ignition, water and steam pressure gauges, safety and vacuum valves and whistle. Gas flow is regulated by a control valve which cuts the main burner in and out to maintain preset steam pressure
