3 inch scale Wallis & Steevens "Simplicity" steam roller - stock code 7971

A 3 inch scale Wallis & Steevens "Simplicity" steam roller, a nicely-built older model in good mechanical order, the boiler has had recent hydraulic test.

Based on the diminutive 3 ton roller built by the Basingstoke company, in 3 inch scale it's of compact size, easy to transport in a small hatchback.

The engine steams and runs well although it requires some work, including replacement safety valves.
