Question on Series VI filters

[mllanos1111]

If I want to use a Polarizer on my R Summicron what do I look for?
I see several Leitz ones but non specifically say Series VI.
I'm assuming that may be because it replaces the retaining ring but not sure.
If anyone has a Leitz part number I can search for that.

Thank you

I don't know a part number either, but these guys seem to have a good supply of various Serie VI filters:

Edit:
I sold my R Summicron and only have an R Summilux now, but I'm wondering how you would rotate the filter?
My Summilux has a hood with a rubberized ring to turn the filter (don't have a polarizer though) but my Summicron had not.
I still have some closeup lenses for the Summicron however

I don't know why they wouldn't make a polarizer they size of the retaining ring and then you could turn it like normal.

I finally found what I was looking for. It's a brand new 44mm Leitz polarizer.
It's just what I thought it would be a filter the size of the Series VI retaining ring.
