Again, Hoppy, there are a LOT of Leitz and Leica polarizing filters which have been made over the past seventy years, and concentrating only on the rather oddball current model is probably a bit unfair, when a basic E39 filter can be had on eBay for $20 or so most days. And when the asker (the Degraded Old English version of the Latin "Querent") identifies what equipment he has and what uses he is intending, then we can be of a lot more assistance. But a blank question of "how do I use a polarizer on a rangefinder camera" is about like asking, "what is the proper tire pressure for my car?". It all depends ...
