[Leica] Polarizing filter

[leicam4pro at yahoo.com (John Biava)]

Nikkors and Hoyas are at least 25 years old. None of these have seperated.   
About the same age for the Leicas.

ones and how old are your 13352 and 
13351's? I doubt its a lack of quality, but more a reflection of how 
well glass and pol films could be cemented together at the time.

One more style everyone's forgotten for good reason -- they had a pin 
sticking out the side, and you'd turn so the shadow was neither to 
the port nor the starboard (and thereby pointing toward the sun).
