Where should I send my UC-Hexanon for repair?

[Archlich]

Today my beloved UC-Hexanon took a hit and although there is no obvious damage, the focusing helicoid seems to be damaged and the level becomes VERY stiff.

It is a pain to see it sitting there, given both its rarity and ergonomics I have got used to. Anyone knows a place where these gems could be serviced? Does DAG take them?

Thanks,
Steve

DAG can definitely fix them. Also, I think John from Focal Point can also do it.
