Great information about Ortho and Litho film thanks. not that this completely relates to the conversation strain BUT: here is some info on this type of film.
I use something from www.freestylesalesco.com called ortho litho film - they make a sheet that is already cut to a 3.9x4.9 size for 4x5 film holder. You get 100 sheets in a box it has a speed of 6, like paper. I develop it in paper developer (Agfa neutol plus) for 1.5 to 2 minutes under a red safelight. I have used Agfa neutol plus at a 1 to 20 dilution. Or Dektol works well too. I have not tried the dektol yet. I dont remember if the dilution was 1 to 20 for that. Wendy Garfinkel
