Polarizer filter

I also notice there are couple of sellers on fleabay offering newest B+W polarizer at amazingly low price. Could it be counterfeit products?

Lots of plastic filters are being sold from Chinese sources; no doubt they find their way onto eBay as well. It wouldn't surprise me if some cocky sellers offer "B+\/\/", "8+W", "B&W" etc. filters, - or even just plastic fakes with the actual B+W logo/brand name printed on.

Correct.
You need a circular polarizer if the camera you are using incorporates any beam splitters - used commonly in a lot of in-camera metering systems.

I too have found this to be necessary for my Nikon and Hasselblad cameras. All polarizers are good for removing window reflections and darkening skies while whitening clouds for color [slide and prints] and black and white films. With wide and very wide angle lenses the sky will darken to different levels dependent on the sun angle.

Thank you, I did not know that Vivitar was Ponder & Best.
 
Similarly BHMC (short for "Bell & Howell / Mamiya Corporation") became OSAWA when Bell & Howell went belly-up. Later, OSAWA also declared bankruptcy -- the largest Japanese bankruptcy until Takata (of airbag infamy) CRASHED!!!

And Mamiya declared bankruptcy too, was restructured, and got out of the 35mm camera business.

The Vivitar and Bell & Howell names have been bought by other firms -- so they still live on in some ways -- similar to Yashica, Minolta, and?????????????????????????
 
It is helpful to differentiate between the products that had names of distributors attached to them - e.g. anything badged Vivitar, Beseler-Topcon and Bell & Howell badged Mamiya cameras - and the products that have badging that relates directly to the manufacturer.
