He may already have this stuff but I bet PKM-25 (Dan Bayer) would love to have hold of the roll and the sheets.

I have a unpened box of 12 Roebuck (I guess before he met Sears ) 3 1/4 x 5 1/2 orthochromatic dry plates. The box is marked extra fast but there isn't any speed on the box; no expiration date either.

A Zeiss Contax camera my father gave me when I was a teenager he brought back from WW11 still had some Zeiss Ikon film in it, as far as I remember, the camera is pre war I don't know when Zeiss stopped marketing this film, but certainly in the 1930s.

My grandfather just recently gave me his Kodak Retina II from the WWII. He also gave me his camera bag and inside it is a roll of exposed 35mm Ansco color film in its aluminum/steel canister. My guess is that the film is from the 50's or maybe 60's. I am in a photography class and really want to develop it. Anybody know what the developer would be? Would it just be regular C-41?

I have just shot a few half-plate sheets of Kodak Ortho-X from I believe 1938. Luckily it is B&W and works fine. Not quite sure if it is giving the full ASA125 though. I have a second un-opened box from the same batch that I shall store for a few more years....

Really?! I always wondered what safety-film meant. That makes sense I guess. You know, the bikes we take for common today were once known as safety bikes, compared to the giant front wheeled 'penny-farthings' of the day.

cheers!

My understanding is that flammable nitrate-base film was replaced with a more stable acetate base, which was safer, and marketed as "safety film." I have never known just how flammable it was, whether it would spontaneously ignite perhaps after some time to oxidize in air, or if the heat of a movie projector would ignite it, or what.

That's correct....the nitrate film is VERY inflammable and needs no oxygen to continue burning once lit. It also decays readily and becomes very unstable. Despite precautions, there were some horrific accidents in the early days of movie theatres.

As regards the Kodachrome found by the OP, there is no chance of it now being processed or even being usable. But it's very collectable, and, if the box, etc., is in good condition, it's really a museum-quality item.

In a lot of 620 film that I purchased for the spools I found a box of Ektachrome develop before Apr, 1949. One end is torn off but there is a sealed roll inside. Whether it is the original I don't know. Interesting to me the box says "Processing directions packed in Kodak EKtachrome Processing Kit" and on another side "This film will not be processed by Eastman Kodak Company".
