Hi.

I have the Telefunken radio type 97 and the tuning mechanism have two washers from a material that is defective.
These washers are between the pulleys where the tuning wire runs.
A mechanism selects the dial cord for FM or other bands.

Would you like to know what is the best material to replace these washers and where can i find it.

The photos better clarify what I want.

Many thanks
