That is what I figured. What is the best material to use to match in
the look and color of the old knob? I searched for black epoxies last
weekend at the usual places with no luck. I was going to fill in the
outer cracks and holes where no "chips" could be found and then
reinforce the inside well, as it broke where the speed tuning handle
mounted (poor packing).

I don't have a clue. I'd ask some scratch-builders. If the knob is
all there and only cracked or chipped, then you have a good start.

I've heard that some car model builders will fill in the joints but
they paint over the filling. I don't know how you can get a good
match. I've seen a dark grey epoxy but not a black. I'd guess
that you can experiment with pigments.

I'm not certain that Hallicrafters put a handle on the SX-101A.
I've seen pictures of this but mine came without a handle.

The other possibility is that you might be able to cast an entirely
new knob. There are "hobby" molding materials, Fimo, Sculpy, that
set up hard. If you used your old knob as a master and made a mold,
it might be possible to make a knob.
