Default Re: Converting a Photo to a Line Drawing?

Chris has raised a good point regarding wafer to wafer component mounting. Folk need to be wary of the practices of some vintage valve radio manufacturers regarding using spare, out of circuit, tags on wafer switches(the same goes for valve holders) for mounting components - not necessarily being switched. Guess they were just being too lazy to fit tag strips on an already confined chassis underside area.
I seem to recall having a rant a few years back(a 1940's Marconi or a Ferranti, cant remember) about the jumble of inter-stage wiring & components where such confusing practices were being used.
