Kodak Tri-X Pan 120 - any idea of age?

[Muggins]

I've just excavated this from a Box Brownie, manufactured in USA but no indication of shoot-by date or film speed. Anyone care to suggest when that green backing paper might date to?

It might all be total speculation as when I checked the cone it had come off a trimmed-down plastic 120 spool (Why? Unless it's something wacky like 35mm under there...), so has been respooled, whatever it is, but I like to know these things...

My sense is that this is 1960s-1970s film.

I have had considerable success developing old films like this using Pyrocat-HD and long, low-agitation semsistand or EMA processing.

For expired film use HC-110 dilution B, preferably original Kodak syrup or the new Adox HC-110 PRO. I always observed that it produced the least fog, and some recent investigations have revealed why. I’ll write some thing about that when I have time.

I tend to go Rodinal 1:100 semi-stand as that wastes least chemistry and effort if there's nothing on it, but I do have a bottle of HC110-clone, so I might just try that.

The camera may take 620 film, and the 120 reels are too large in diameter to fit... unless you trim them down a bit!

True! It is indeed a 620 Brownie, might just be that someone only had a roll of 120 to hand. Hadn't thought of that.

Would a roll of that age have been sold on a plastic spool? If so, we probably have an answer. They made a good job of the 120 spool, too, very neatly trimmed down. Then didn’t finish the roll. I guess we'll never find out why.

Any results will be posted here when I get round to developing...

Now my neg sleeves have arrived I can start developing again!

Are you suggesting semi-stand with that dilution, please?

If developing by hand I use less but not less frequent agitation. Exactly how it goes is always dependent on the storage and other ineffable factors.

 

[Muggins]

Indeed! I've had some rolls that looked fine, some blank, and some that looked to have been boiled in old jockstraps. I think everyone whose developed found film has.

What is the EI for boiled jockstraps?

40.

40.

I can see I am going to have to look out a particularly comic example... I'm thinking of the roll from a VP Twin that must have been taken by someone who had been an executioner in a previous existence judging by the number of heads they'd cut off... and then the film had aged badly too. Its grim!

 

[Muggins]

This one is jockstraps. I think I may be looking at emulsion rolling off the base on the part that was exposed first, though I'll have a better idea when it's dry.

 

[Muggins]

OK, the car is one I took to finish the roll. The other is one of the four frames just distinguishable from the fog - three are like this. Looking closer I don't think it's the emulsion rolling off, but what the hell is it?
