Sold January 2025 Back to Archive

It's been checked over in the workshop and has had hydraulic and steam tests, with new certification issued. Words below and pictures opposite are from the last time it was here, the video was shot in recent days.

In 2002 we sold a 3 inch Atkinson which had won a Gold Medal and the Hughes Trophy at the Sandown Model Engineering Exhibition in 2000 - a superb model, it's taken us nearly twenty years to find anything approaching, let alone surpassing it.

However, we think this one does just that - an impeccably built engine, the work of a prolific, highly talented engineer responsible for an impressive tally of stationary engines, locomotives and road vehicles.

A few of examples of his work which have passed through our hands in recent times include an open crank hopper-cooled engine, horizontal twin IC engine, vertical compound steam engine, vertical twin IC engine, seven cylinder radial engine and a seven cylinder "Monosoupape" rotary engine - all built to the same, superb standard.

Unsteamed from new, the Atkinson is in "ex-works" condition throughout. Fit and finish of all parts is excellent, the builder displaying equal facility in metal and woodwork.

Update - January 2024

The boiler had an initial twice working pressure test at 200psi for 100psi working back in 2022, with new certification issued for a repeat test at 150psi in recent days. Water feed is by hand and mechanical pump - the injector's more show than go.

The engine steams freely and runs like a sewing machine, the video below was taken last week.
