Sheet Film Notch Codes

[Marc Akemann]

I have a half dozen 9x12 sheet film holders (Zeiss Ikon 665/7) with film in them. I sacrificed one of them so I could id the film. It has two rectangular notches on the right side and I could not find this code anywhere.

Measurements: Coming in from the right side, emulsion side up, the first notch is 5mm from the edge and 3mm wide. Then, there is 3mm of film and then another identical 3mm wide notch. 1mm is the other dimension for the notches.

I've looked at the following links to no avail: http://web.archive.org/web/20030208093848/http://www.srv.net/~vail/notch.htm

I also looked at Simmons' book, "Using the View Camera". (1987 edition).

I don't know how long the film has been loaded but it's been within the last 12 years, I think. I purchased these film holders in a wooden box along with a beautiful Zeiss Ikon Maximar 207/7 and an extra box of 3 1/4 x 4 1/4 Kodak Cut Film Sheaths (Zeiss Ikon 725/4). There was a receipt in the box for this 'kit' dated 1997. I suppose it's possible the owner of this equipment previous to '97 could have loaded these, too. So I really don't know when the 9x12 sheaths were loaded.

I guess I could sacrifice another sheet and develop in D76 for, what, 6 to 10 minutes? Maybe the name of the film will show on an edge. Can anyone help in identifying the film?

can you make a scan of the film so we can see
the notches ?

it seems like it could be : pro 100 prn
but the first rectangle has angular sides, not rt angles

not sure if you saw this: (there was a url link here which no longer exists)
it has a few that nicolai's page doesn't include ...

sometimes there was a universal notch for low volume films
which was 1 ( or maybe it was 2? ) rectangular notches.
whenever i ordered SO132 it had them ..

Hey John, thanks for the help. The link you provided looks like the same info as the first link I show in my original message. You're right about the universal notch code for low volume & special order products. The chart shows 1 notch, though. Darn!

Attached is a scan of the film in question. It's as close to life size as I could get it.

edit: I added a second image so the 'X' isn't in the way of the notches.

Looking at the "Acetate Negative Survey", which has a huge catalog with all Kodak's notch code patterns, and all the films each have been associated with, it's not a Kodak notch code.

They do show that as one of the codes used for DuPont "Defender" film. But they have no historical source material on that notch code -- DuPont's film records are gone.

Also, the color of the emulsion definitely looks like a B&W film, maybe one with gold doping (similar to Super XX).

Looks like Ansco/GAF.

I think you're right. I just found the following info on the mystery film. It's called Ansco Triple S Pan film: http://www.mattosbornephotography.com/Ansco/ansco_notch_codes.pdf .
I found another link that shows it to be a film with a daylight EI of 200: http://www.jollinger.com/photo/cam-coll/manuals/meters/Skan_ViewFinder.pdf
And I found a 1950 ad on eBay for this film: http://tinyurl.com/yfruqxt

Thanks for all the help everyone. These kinds of things drive me crazy. Now I can sleep tonight. I'll ask for suggestions on how to shoot and process this film later...on a different thread.
