After more consultation with TRF, it appears likely that the earlier part
had longer threads - the current rheostat superseded another one that
superseded the original, all many years ago. On metal-dash TR4's it was no
problem anyway. On TR4A's, TR5/350's, and TR6's, the rheostat was moved to
the center panel below the dash, where it's only thin metal.
Only the wood-dash TR4's appear to have a conflict. Wood dashes on TR4's
had originally been a factory option, but were apparently made standard at
the end of TR4 production. Mine appears to be from the factory, it's in the
right commission number range to have had a wood dash, and the metal behind
it is indeed the metal that goes with a wood dash, as opposed to a metal
dash that someone put wood over. They're obviously different, and the
difference is simple to spot when the glovebox is open.
And the DPO didn't want a rheostat - in fact he wired around all the
original switches, using a toggle-switch panel below the dash. Glad he
didn't throw anything else away (except the ash tray, which got the same
wood plug treatment).
Anyway, I've got to either find a good original rheostat, or make up an
extension thread for the new rheostat I have. Geez I wish the old TV
repair parts store was still here. If I can't find something standard to
screw together (maybe a lamp parts supplier ?), I'll probably be spending
some quality time with the lathe.
Thanks!
