Wow, never seen this one...nice scrap job.

Sorry about what you have to deal with, it also looks like there is flux or some other compound (stain) on the circuit board. Someone may have tried to fix/break gauges...

Try 928 Intl for a board. If you have a good solder iron and have a good hand, you possibly could re-solder over the circuit. I would try to find a suitable replacement.

Mr. Merlin may have a magic wand.
