2 inch scale Ransomes, Sims & Jefferies DCC steam tractor

A finely made 2 inch scale Ransomes, Sims & Jefferies 4nhp double crank compound steam tractor, built to the John Haining design, serialised in "Model Engineer" magazine from 1977.

A rare model - in the last twenty years we've only over had one other.

The silver soldered copper boiler has had a twice working pressure hydraulic test, with new certification issued. The motion is silky smooth to turn over, the engine has been tested on air, running as well as it looks; slight leakage past the regulator was noted.

The engine steams freely and runs well, however the scale safety valves - whilst coping with normal running conditions - accumulate when the fire is forced with the blower. Either the valves or blower will require work to rectify.

The injector is a dummy, piped through to an effective hand pump in the belly tank - the engine also has a mechanical pump. We love the detail on this one - including the hand made steering chains (with a few spare links in the spares box), double nutted bearing caps and eccentric strap wick oilers.

Complete with a stand for the canopy when not in use and a purpose built storage crate - both as nicely made as the engine itself.
