Whats your bid on this mystery 81D?

[Creighton]

Very nice machine and score.

There is no reason to waste money on a restoration.
Think you will find it will clean up as an outstanding original. Worth far more than a restored machine.

I would start with using a micro-fiber towel and hot water, Wipe down first just hot water. That gets the dust layer off.
Next: New MF towels and wipe down with Windex Original. Best I've found to get funky stink off machines.
I use a couple of Dawn soap drops heated in water. mix to wipe the exterior one more time.

Next scare up some Flitz polish. Not available local here anymore. May need to go to the web for that. It is outstanding.
I finish with Meguiars Ultimate Quik Wax.

At most $250 in stuff that will be handy for the next machine.
