4′ 7½″ diam., 14 oval spokes, rect inner rim, apparent tread 4″.
Hub 16″ face dia., 2″ out from the tyre (some dimensions estimated).

I do not know if the prototype driving wheel weights are surface mounted plates or are cast in so have not included them. The photo in Russell vol. 2: fig 50, shows the driven wheels with one end of a weight more or less in line with the crank and no indication of the weights in the coupled wheels.

Casting: 62.4mm tread dia., 53.4 mm i/d., hub 2.5 mm out from the tyre.
