3/4 inch scale Allchin Showmans engine

A 3/4 inch scale Allchin Showmans engine by Michael Holden of Banbury - I've no idea how many of these they made, we get them in very occasionally. Finely engineered and lots of detail, they run well. This one's gas-fired, we've also got a coal-fired agricultural engine version of the same thing.

Silver soldered gas-fired boiler, feed by mechanical pump. Gunmetal cylinder with slide valve actuated by Stephenon's gear, pole reverser, displacement lubricator. Two road speeds.
