Leitz was forbidden to use the Smakula vacuum 
coating technology owned by Zeiss until 1960, so 
they were forced to use a drip-coating method in 
the interim which often caused the coating to be 
soft and evanescent.  After 1960, all Leitz/Leica coatings are really hard.

There is a good book which you might want to 
acquire, entitled NON-LEITZ LEICA THREAD-MOUNT 
LENSES:  A 39mm DIVERSITY, as this matter is 
discussed there.  The book is MOST highly 
recommended -- for that matter, Jeffrey Smith 
needs to get a copy also, to see all the 5cm/50mm 
lenses which are missing from his arsenal.
