I'm thinking of buying this Admiral

On wire wound pots (cough rheostats cough) you can often bridge the open and get the pot usable again.

In that rheostats case, you may need to add series resistance (given a lot of turns look bad) and reverse the ends of the pot so the wiper/rotor does not rest in the bad zone when focus is adjusted. Necessity (or cheapness and poor parts availability) is the mother of invention (but does it have Zappa too?).

My first thought as well, but it's pretty screwed up. You can see a large section of turns aren't damaged, but the ring they're on is wrinkled inwards.
