[TR] TR3 antenna placement

[Randall]

For the US, radio antennas were generally installed by the dealer anyway,
who may or may not have paid any attention to the location in the
instructions.  That said, all of my TRs with antenna holes have had them in
the RH fender, roughly where the instructions show.

That's curious about your speaker cutout.  I'm pretty sure all of mine have
been on the right.  On TS39781LO you could see original paint on the edges
of the hole, so it was clearly cut before the body was dipped.  But it was
also quite a bit larger than 6", more like 10" IIRC.  I could not find a
modern full-range speaker that would fit the hole, so I made a mounting ring
to accept a 6" speaker.
