Here is the part of the project relating to the Ittok tonearm.
As I remember it, this was “bearing strip / service repair”, as you suggest.
I made a deliberate choice to leave the original internal tonearm wiring. These were fine and didn’t need any work. (Again, a desire to keep things original). The key thing was bearings were replaced. Good as new.
I think it’s amazing that an item 35+ years young can be restored in this way.
Also that skilled artisan craftsmen are out there and can provide these services.
