Yes, Marc ;-) However I'm pretty sure that Ric is shooting with a modern M. 
Also he just wanted suggestions on how to use it. Same
technique for the old Leica types, nicht wahr?

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 ...
