the world moved on and soviet stayed with the old lubricants
Exactly, yes.
I assume that was pre war?
Yes, but they should be working again now.
where they still doing CLA on them before that?
In one of Arsenal's buildings. This factory is like a city in a city. Several buildings were stolen, but the majority still belongs to the factory and is used. They even restored (polishing+re-coating) a frontal lens for my Arsat H on the same equipment it once was manufactured and made an entirely new lens for my friend's nikkor
I didn't contact them now tho, Arsenal's production areas may have been used to accommodate the production lines from damaged factories, and camera repairing is very far from critical needs rn
