Want to Buy WTB Hoya B30 K2 Yellow filter

[NWT Ron]

I'm located in Canada (Yellowknife). On a recent trip to Ottawa I picked up a Yashica 635 with a few Hoya B30 filters, unfortunately the yellow K2 is missing. I'm looking for one. Was a polarizer also available in this type of mount?

Thanks to a PM I've been in touch with KEH about buying their bargain brand equivalents.

The Minolta Autopol is probably the best polarizer solution I've seen for TLR cameras, but is fairly scarce and expensive when they do show up for sale.

When I purchased the yellow filter at I also asked about a polarizer. They had one, brand unknown in their system, so I picked it up too and had them both put in the mail.

Thanks for the recommendation, there isn't much help locally.
