3 inch scale Ruston & Proctor steam tractor with driving trolley

A finely-built Ruston Proctor SD tractor in 3 inch scale - had them in 2 inch, 4 inch, 6 inch and full-size before, but never seen a 3 inch one, this one makes the complete set!

Sprung both ends, as per the prototype, the engine runs particularly nicely - it's a lovely thing to drive, steam freely and runs along very well with clear, square exhaust beats. There's a short video of it running here in the yard.

We've fitted the regulator with a PTFE-faced valve - this is a routine job we do for engines that come in with leaking regulators; the replacement valve providing both an effective seal and also a much lighter, smoother action which makes driving a nicer experience (Connor is our regulator expert - he'd just finished machining one up and fitting it to the 7 1/4 inch gauge Duchess that went out last week when the Ruston landed on his bench).

Complete with a driving truck and a pair of curious looking traction engine lamps (mercifully quickly detachable).
