Most of my cameras are older than you Matt
(Maybe that should be many not most).
I do service LF cameras, I'll strip them even wash them and Im'm not joking either, owever I do know what I'm doing. Washing in hot water might sound severe but hey bellows and focus hood, plus lens board, removed (possibly rage finde as well)is no big deal with Linhof Technika or Clobne, And in sme cases I want the coveing material to come off as well. Then I can recover in new material.
But that's an extreme, some CLA's are a half hour job others need new parts fabricated. People ask what camera and the OP seems reluctant to say..
This was a CLA i did 2020
