Disc trailing and tender wheels: I first made patterns for the 15F from a published drawing by Ian Beattie. It showed trailing and tender wheels at 2' 10" diameter with 10 spokes. I have seen a photograph of a 15F trailing wheel as a disc wheel, but have not come across any information to support the 2' 10" wheels having spokes. If you require 2' 10" wheels with spokes, substitute H104 for H332 at the same price.
