Driving wheels
The following is a list showing the prototype feet and inch size with the metric equivalent size
to the nearest millimetre in square brackets.
The sizes indicated in red are the equivalent prototype sizes, if the
wheel is used on a model with a scale of 3.5mm : 1ft. (HO) Please note that the sizes in
red are an approximation only.
Abbreviations: C.O.S. - Crank on spoke, C.B.S. - Crank between spoke, O.S.F. - Outside
