Advice on Developing 75yo film + others

[1jz]

I don't know where to start with this lot. So maybe someone can suggest an approximate speed of what 1935 film is likely to be.
Has anyone developed film this old before? Any suggestions for developer and time?

There could be some pretty interesting photos so i want to take a cautious approach rather than just chucking it in d76 for however long. Can anyone guess at date and speed for the super xx and fp3?
Thanks

no advice but you have me curious of whats on them

I've been making my way through a long roll of aerial recon super-xx film from the '50's. The can says it has an exposure index of 100. Six minutes in Rodinal 1+25 seems to be sufficient. A bit foggy, though.

What you probably want to do is a clip-test. Snip off half a dozen frames and develop, then decide if you need more or less time.

Thanks for the info on the xx, will give that a a shot. Anyone want to guess what speed the 1935 film would be , asa10?

FP3 is about ISO 125 and made into the 1960's at least. Using current FP4 times in D-76 should be close enough.

I have developed some Pan film (120 format) from the mid Fifties...the stuff was in it's original packaging (all sealed up like new) but I was unable to get anything to show up on it...I even tried to develop a few unexposed rolls but got nothing...when I say nothing I mean the film was all cloudy and dark not clear...no markings were visible along the edges...

Good Luck with yours...
