Where do you get the parts and supplies?
About 5 years ago I tried to get an authorized repair shop to work on the meter of my Nikon F2SB, which slowly faded over the years.
They flat out refused to do it.

This page opens on a Canon but he handles all makes.
The mirrow damper is the tricky part, my fingers don't work like they used to.
