Are 850 mk3 Commando's Veglia rev counters repairable?

My Veglia rev counter still works but could do with a service and cosmetic refresh, I have read various posts that say these are not repairable?
As I am in NZ is there any local members here that could recommend a service agent for repairs?
Thanks

Yes they are repairable, I had my veglia apart to cure a wildly swinging needle, all over the place. When i got it apart and delved into the inner workings i found the little brass bush on the drag cup was worn out causing the drag cup to catch on the magnet and so swing the needle about. A bit of lathe work and the use of some clock makers broaches cured that. It helped that i had already made the equipment to roll off the Bezel and roll it back on.

They were used a lot on Italian bikes of the same era, look for an Italian clock restorer.
