Here's an example of the typical dirty contacts and the damage lubricants can do to moving parts.
This is a score reel EOS switch. Now keep in mind all the score reels looked to be in excellent condition, but the underlying problems are still there. This is simply a piece of cardboard wedged inbetween the contacts, and swiped once !
Coils sleeves - the leftmost one is filthy !
The MAMMOTH job of rebuilding all the score reels is finally completed !
Moving on to the backglass. There is minor lifting that needs to be fixed before I mask out the individual score reel windows. So rather than risk removing more flakes of paint (simply by cleaning them), I'm going to seal the lower sections - but I mask out the entire score reel section. I will mask these correctly once the surrounding areas are sealed.
The sealing of the backglass will need 3 coats. this will be the first - and the reason for this quick seal is that I don't want to lose any more artwork.
