Tiffen / Kodak (Wratten) Filter Equivalence?

[lepidus7]

I have used Tiffen #25 Red in 35mm arena (for shooting black & white film) and am looking for a (near) equivalent in a 3 x 3" (75 x 75mm) square gelatin or glass usable in my Mamiya G3 Bellows . Although I can find wavelengths blocked by Kodak Wratten filters, I am unable to find similar data on TIffen filters.

More specifically: Is the Kodak 75mm #25 Red Tricolor Wratten 2 Optical Filter (3 x 3") equivalent to Tiffen Red Color Contrast #25?

Any charts, tables or recommendations which compare the round glass Tiffen filters to their 3 x 3" square counterparts (any manufacturer) for the use of black & white film contrast will be greatly appreciated.

The Tiffen filter info you want is at the bottom of page 25 of the PDF at http://www.tiffen.com/userimages2/Filters/Tiffen_BFILT_Broch_0413.pdf and the Kodak filter data can be found on page 174 of the PDF at https://archive.org/stream/KodakReferenceHandbook#page/n173/mode/2up

Thanks. Your reply was exactly what I needed to end my search. I had struck out and knew that there were experienced professionals out there that would know the right information. Now, it's as simple as ordering from an on-line photo retailer. Thanks for opening a new chapter in my progress to become a better (medium format) photographer.
