4 1/2 inch scale Wallis & Steevens "Simplicity" roller

An early stage 4 1/2 inch scale Wallis & Steevens "Simplicity" steam roller to the Plastow design.

Including flanged boiler material, parts and most of the significant castings, the model is a straightforward build requiring only modest-sized workshop equipment.

Work to date is to a good standard and includes:

• Set of front and rear rolls
• Machined forks
• Machined crankshaft and second shaft, assembled into hornplates complete with stub axles
• Steering gear and quadrant
• Machined piston with rings
• Machined valve and pump eccentic straps, pump sheave
• Rear hubcaps
• Machined final drive gear blanks

We've had several of these in over the years in both 3 inch and 4 1/2 inch scale - there are some pictures of one of the larger engines in the archive here.
