Let's identify this ancient sheet film.

I recently picked up a 3.25x4.25 graflex RB that had a bag magazine attached, with a few sheets exposed. The topmost sheet was already ruined (no dark slide present), so I emptied the magazine into a light tight container and sacrificed that ruined sheet for id purposes. Usually I'm pretty decent at identifying old sheet film that comes in holders, but this one has me stumped.

I have no idea if it's even b&w; the base is very thick (thicker than any 4x5 sheets I've shot, I think), and very glossy on the base side. It has a purplish tint to the base. The notch code is simply one ----v--, and stamped into the edge is 'KODAK---S°AFETY---FILM 111'. This 111 seems like a pretty non-standard kodak emulsion number. Anyone have some guesses to what it might be, so I can give a whirl at developing the exposed sheets?

Thanks!

Haven’t come across this film, hamradio.

But searching I found this link:

Kodak Film Number to Film Type Cross Reference Table

Looking at the list there’s a ‘SO 111’ but no information about it. 🙁

Look Here: http://gawainweaver.com/images/uploads/Horvath_AcetateNegativeSurvey.pdf

According to the illustrations at the very end of this survey (and I think it's #31, as it's the only single notch Kodak film illustrated there), it could be several listed.

Looking at the Photographic Data for Kodak Technical Representatives of 1950 there is but one film with the single 'v' notch. It is the Kodak Super Panchro-Press Type B Sheet Film.

The single round sided notch 'u' is Daylight Ektachrome.

Thanks for the input, all!

I put it in a drum with hc110b for 7min, and ended up with nothing. Black negs, with faint outlines where the septums held the film, and outlines of the number of each septum. Either someone opened the magazine in the last 50 or so years, or it just fogged that heavily. Oh well.
