What series filter sizes for the 10", 12", and 14" Commercial Ektars?
Thank you.

My 14" takes 72mm filters. That's all I got!

My old Kodak book indicates Series VIII for the 10 and 12 inch and Series IX for the 14 inch.

Thanks, Keith.
Does it happen to mention the outer diameter for fitting the slip-on adapter?

According to "Kodak Products for the Professional", January, 1961:
8 1/2" Commercial Ektar Filter Ring Adapter - 1 3/4" - Series 7
10" Commercial Ektar Filter Ring Adapter - 2 1/8"" - Series 8
12" Commercial Ektar Filter Ring Adapter - 2 1/2" - Series 8
14" Commercial Ektar Filter Ring Adapter - No. 91 - Series 9
I confirmed the first three by measuring my lenses. I wasn't sure what No. 91 was, so I measured my 14" Commercial Ektar and got 2 15/16" (2.9375").

Kerry,
Thank you for your post. I just picked up some series 7 push on filters for a Ektar 210mm. I'd been wondering how to get a filter on this lens. Also found some modern filter adapters that screw into the series 7 that mount modern filter sizes.

As Kerry mentioned the 12 inch takes a 2.5 inch (63.5 mm) adapter. Nice thing about that is that 67mm filters screw into that adapter.
