Maxitrak Aveling steam tractor

A well-kept example of Maxitrak's ever-popular Aveling steam tractor. Complete with capacious driving truck (it was actually big enough for Jon and me, which is more than can be said for some 4 inch scale trucks that come in), it's a free-steaming, easy to drive engine.

Silver soldered copper boiler, working pressure 100psi, twin safety valves, feed by injector and mechanical pump - the injector is set up to draw cold water from a tank in the driving truck. Cast iron cylinder with slide valve actuated by Stephenson's gear with pole reverser, mechanical lubricator. Two road speeds).
