I would love to be able to say how good/bad Zeiss-Opton 2.8 80 mm Tessars
are.

But, alas, i haven't tested the ones i have yet, since they need cleaning
very badly. No point testing a dirty lens.
I have asked the Hasselblad Users brethren (mine are in "ancient" Hasselblad
mount) if anyone knows how to get to the rear lens group, but so far no
answer.
So maybe there is someone on this list who can tell me how to disassemble
these lenses (in such a way that they can be reassembled again)? Or knows of
any resources available anywhere that might help?
I'd be grateful for any and all assistance!
