[Leica] Leica M9 sensor corrossion

[Frank Filippone]

I meant to add that you need to figure out WHICH cover plate glass you want installed.   It was the coating on the cover plate that was not corrosion 
resistant that caused the problem  Leica was told this but insisted on using it anyway.  Or so goes the story at the time.

Kodak made the original sensor with cover plate.  Is of type KAF-18500

Leica states that the original cover glass is of type S8612.  This does not easily correlate with the rest of the info we have.

B55 was reported by Leica as the replaced cover plate glass.  Kolari offers B39 and B61 ( as of their current webpage).
