Halfway through the FR brake No2 conversion from a Dundas Models quarryman's coach kit. Logically, as this follows the prototype conversion, it should be fairly straight forward, but of course it doesn't quite work out like that. I'm not sure that (at least with the body) that it wouldn't be better to start from scratch as there are a load of compromises and you have to alter every single part in some way. Is starting with a kit necessarily a timesaver? Not necessarily so.
