[TR] TR3a control head piece

[Jim Wallace]

Years ago I took my control head complete with tube-that-holds-wiring out as
an assembly, and stored it ever so carefully on a shelf. Of course being
round it rolls, and - yeah it fell off the shelf.A chunk of bakelite broke
off as seen here:

and I saved it, thinking it is reasonably out of sight and I can probably JB
Weld it back on. And then it got lost somehow. I have really searched but it
is the sort of bit that could have been swept up off the floor along with
other junk.

Does anyone by any chance have an extra one of these pieces? I don't see
where they can be bought new.
TIA,
Jim
