I've this Contessamat SBE sitting on my desk to CLA, i've done it partly allready, but i would need a service manual to check out and adjust the guts of it (shutter, speeds, adjustments, cell and its galvanometer...).
Hope someone have it, and could send it by email !
Have you tried to contact Zeiss?
They might have one in their archives.
Otherwise send your camera to a good Zeiss repairer.
I doubt any one here has a repair manual other than skilled and trained repairers.
Thx a lot for your replies !
I'm moving soon in another country for work, here's why i would prefer buying a pdf version instead of a written one, less weight to carry...
But yep, Zeiss could be worth a try, thx for the idea !
