yes this was a twin cylinder steam engine with slide valve reversing gear, perhaps made by an engineroom fitter in the style of engines he was familiar with but the valve chests are rather short and the reversing gear control wheel way out of scale so perhaps something he found.

Value way out too. Pity that a decent modeller didn't find it at the boot sale.

I saw the original programme a little while back and think I saw the same or similar engine subsequently for sale on fleabay. (the oversize handwheel and oversquare cylinders stuck in my memory)

Two cylinders the same size, not compounded, where reversing is a major function. Mill engines and pumping engines only run one way. Although ship engines reverse they need to be energy efficient, hence small HP and big LP cylinders, which this model doesn't have.

My guess it's a model rolling mill engine, the sort where hot metal is passed to and fro through a pair of rollers to make sheet, strip, angle girders and rails. Rolling engines need to be powerful rather than efficient, and the operator continually starts, stops and reverses them, which might explain the giant control wheel.
