Possibly cork will be the way to go.
I already sacrificed a felt mat to it. The platter was grinding and I think it's supposed to have a bushing at the top of the spindle well. I cut a piece from that mat, soaked it in oil and dropped the platter axle though that. It helped but I later found some thickish leather and added that and it improved again.
I also dissembled the idler assembly, cleaned a lot of crud from under or on those surfaces, and coaxed oil into the tubes on the motor. It's a little motor-noisy but not really bad. The platter and mat got a wash and scrub. The plinth has been cleaned and treated with Howard's.
I removed the arm. It's a dedicated mono arm but had a B&O cartridge (SP-12?) wired for mono. The arm bearings are very good but the pitting is pretty bad. So far I took it somewhat apart to aid in cleaning but the surfaces will take some work and won't retain their original finish.
