A finely made Fowler A7 agricultural engine to the MJ Engineering design. Completed in the mid 1990s, it has been unused since 2002. Arriving at the workshop with a liberal coating of oily dust, Jack spent a happy day cleaning it last week. The work of an experienced engineer, fit and finish is good throughout, there are nice details like the blowdown valve operated by an extended T-handle brought up just above the rear of the running board.
Silver soldered copper boiler by Bishop Ellis, 80psi working pressure, feed by mechanical pump and injector with auxiliary double-acting hand pump in the tender. Cast iron cylinder with slide valve actuated by Stephenson's gear with pole reverser, Watt-type governor. Mechanical lubricator.
The engine was originally built to be coal-fired, it was latterly fired on gas for convenience - the gas burner remains fitted above the grate, an oil separator fitted in the smokebox beneath a down-turned blast pipe (the engine had no need of a forced draught when running on gas). It could be put back into coal-burning form easily, there are minor jobs to be done including straightening out a bent whistle lever.
