Reviving a Triebert Brevert C LP clarinet

[tseligas]

Good call on the screws. I can't tell unless I unassemble about the hole. It has nothing to do with the spring though. The spring goes to the pivot point of La and ends behind the cork.

Ok I got 2 oils.
3 in ONE
and ELmer's Slide All.

I vote for Elmer cause it is dry, not oily or stainy. It may be tougher to penetrate though.
