Does anyone know where I can buy two of the aluminum disks that are used on the Hallicrafters SX-110 radio knobs?

I need two of the ones for the main tuning and spread band knobs. The Aluminum disks are 0.78 inches in diameter and are not flat.

Thanks
Tom

Know what your talking about. Knobs with that convex disk in them fall out all the time.

Good luck finding just the inserts. May have to buy the complete knob instead.
