3 inch scale 6nhp Burrell agricultural engine - stock code 12610

A 3 inch scale 6nhp Burrell agricultural engine, built to exhibition standard using the Plastow drawings. The engine was test-steamed on completion, then stripped and painted - it has been on display even since, remaining in as-new condition throughout.

Machining is very crisp, fit and finish of motionwork and valve gear excellent. Platework is neatly formed and fitted, the paintwork finely executed and hand-lined to a high standard. We love the little details, rarely seen in a model at this scale, including the beautifully shaped and engraved "working position" indicators on the reverser stand and the oil pots fitted to the steering worm and wheel.

The silver soldered copper boiler has had a twice working pressure hydraulic test with new certification issued, the engine runs well on air in either direction. There were minor leaks from fittings - not unusual in any new engine - which will require attention when commissioning for steam.

A very fine piece of engineering, one of the nicest Burrells we've had in this scale.
