Update....
I'm still a bit incredulous, but the SW band is now working. I knew the oscillator was working, so I connected my signal generator to the grid cap of the mixer tube. Maybe the RF coil was bad. I could hear the generator as expected. But I noticed that when I jostled the connector it seemed to receive. The connection with the cap was very loose. I crushed the connector a bit to tighten it. It was fine after that. Why it worked on the other bands, I don't know. The only thing I can think of is that all were not performing well and that band's alignment is the worst and that was enough to kill it.
The dial assembly is still a problem.
Putting things back together I first slipped "A" the reflector over the drum. Next the mask, "B". Next the spacer ring, "C". Next the dial, "D". Next the thing that holds the station tabs and holds the whole lot together, "E". Can't see it here.
The problem is when I tighten the screws on "E", it presses the dial against the spacer (OK), pressing the spacer against the mask (not OK) and the mask against the reflector and the reflector against the "flange" (can't see it) on the drum.
Since the mask doesn't on the spacer, it gets compressed and would like to turn with the dial. Did I put this together incorrectly? It sure doesn't look like that when I look at my disassembly photos.

Can't think of anything witty.
