Simon, I do remember that I was influenced at the time by a G1MRA member who I used to meet at get-t0-gethers in the Somerset area (Maurice ????? ) who modelled two rail electric and to finer track standards. I don't think Proto:32 (or whatever it is called ) had appeared by that time. The wheel castings were from Locosteam (now long gone) and I spent long, dirty hours filing the spokes down to be much finer than they were originally. Jim.
