Mystery Sheet Film

[markjwyatt]

I am looking at a 1940s era (late 40s likely 1946-1949) 4x5 B&W sheet film printed "Kodak Safety Film 241". The notch pattern is as follows. (from R-L: Large rectangular cut, large flat, v-notch, large flat, v-notch, small flat, v-notch). Some Ortho films come close, but none I can find have the v-notch, large flat then two v-notches, or the initial rectangular cut, large flat than v-notch.. Any ideas?

V-V----V----|_|
(from R-L: Large rectangular cut, large flat, v-notch, large flat, v-notch, small flat, v-notch)

For example, Kodak Super Speed Ortho Portrait Sheet Film had
V-V-V----|_|
(from R-L: Large rectangular cut, large flat, v-notch, small flat, v-notch, small flat, v-notch)

And Kodak Commercial Matte had
V-V----V-|_|
(from R-L: Large rectangular cut, small flat, v-notch, large flat, v-notch, small flat, v-notch)

Finally, Commercial Process Ortho had
V-V----|_|
(from R-L: Large rectangular cut, large flat, v-notch, small flat, v-notch)

I have a 1945 Kodak Reference Book , and it might be Super Pancro-Press Type B. Notch code is below:

That is it! Thank you. I cold only find a Kodak 1953 reference book online. Interesting. This is one of my dad's old negatives. Mostly he used Ansco Super Pan Press and Super S Pan. Love Photrio!

I've loaded up some 4x5 sheets of this to shoot tomorrow, and just glanced at the data sheet that was in the box. Even though the film expired in 1945, it's claiming a daylight speed of 500. For a 1940's emulsion, that seems awfully high to me. Can it be true?
