Anyone ever repaired a C-90 that has been dropped?

I repaired an F-50 this last weekend. Pretty nice amp by the way!
It had fallen backward while the band was setting up.
The volume was really low out of the amp.
The guy had tried new tubes already, so I pulled the chassis and plugged it into my cabinet because I know what it sounds like.

Low and behold, he just needed a speaker.
His speaker read good on a multi-meter, but the cone will not move.

I'm guessing that the voice coil is warped or stuck.

Anyway, before I trash it, I thought I would ask if anyone has repaired one like this.

Sounds like the frame is warped from a drop, this puts the voicecoil out of alignment. I've heard of a couple speaker repair shops claiming to be able to fix (Miller Sound Pennsylvania) this but it is very difficult to ever get the magnet lined back up.

I was guessing that it was beyond repair.
Bummer! I sold him the C-90 I had planned on using in a DC-3 that's on it's way.

Good thing I still have a couple of Heritage 30's!
