8 HP Single Cylinder Traction Engine

The Wallis & Steevens traction engine in 3" Scale has been developed from drawings and patterns originally designed by Mr Smith who owned the engine no 7269 Panther built in 1912. The drawings have been scaled from the full size engine and thus represent a faithful reproduction of the original.

All of the castings are finely detailed.

The Wallis is a similar size to our 3" Fowler A7 and makes into a highly powerful, yet not too large a model which is ideal for rallys.
