3 inch scale Wallis & Steevens "Simplicity" steam roller - stock code 10324

A part-built 3 inch scale Wallis & Steevens "Simplicity" steam roller to the Plastow design.

Work to date includes a boiler barrel with smokebox and headstock assembly with forks, machined cylinder, front and rear rolls, crankshaft with valve gear and motionwork, gearing including differential, motion cover, canopy, parts for steering gear and belly tank.

With the full-sized engines only scaling three tons, it makes for an easy to handle model in this scale. A popular, rather quirky design with its diagonally disposed boiler and all geared steering - if you want to see what they look like when complete, we sold a particularly nice one back in 2017 - there are pictures in the archive here.
