this is from the first series of Plan objectives Leitz made, around 1960. "C" means "coated".
The objectives of this series are of different correction state: The Plan 100 is a actually a Planapo 100!
Unfortunately this is also one of the few objectives from Leitz that tend frequently to delaminate. So you should check with a phase telecope whether it is ok or not
I have two: One delaminated, one with loose front lens - a perfect DIY kit for the patient microscope repairer! :lol:
