We sold this one last year, it's recently come back from a long-time customer in part exchange for a four inch scale portable engine. Unused since we last sold it, condition remains unchanged - words below and pictures opposite are from last time it was here.

A Wallis & Steevens "Simplicity" steam roller, a nicely-built older model in good mechanical order.

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.

In steam yesterday, it runs well enough although has a couple of jobs need doing over winter, including attention to a leaky regulator and ineffective injector - likely caused by a leaking clack valve.
