Old TXP

[Alan Johnson]

I bought some expired 220 when it became apparent that no new 220 production is likely to appear.

The rolls were unboxed and do not have a Kodak logo.
Any ideas when this was produced?
Assuming it was not kept frozen, what EI to shoot it at?
Thanks.

This looks like packaging I have for 120 rolls of other Kodak films from the late 90s. I believe that this packaging was used as early as the mid-80's though (someone correct me if that's wrong). I've seen Vericolor III in this packaging from the late 80's I believe. I'd try shooting it at 50 or 100 and see how it goes.

Use EI 125 and 250.

You could unwind one of the rolls and extract a few inches of film from the end (putting it back together carefully after) and test that exposed at 50, 100, and 200. If you have a large format camera, you could tape it into a film holder and do all three exposures on the same strip of film (pull the darkslide 1/3 of the way, expose at 100, pull another 1/3, expose at 200, pull another 1/3, expose at 200 - that'd kinda approximate it).

Alternatively, you could expose at 80 (a nice safe value) or even 100. Then, when you have three or four exposures left on the first roll, just take the same picture over and over. Cut the last inches off the roll when you're loading onto a reel. Cut that in three sections. Develop one normally, check how it looks, adjust your time, develop the next, check and adjust, develop the last to confirm.

I have Plus-X and Verichrome Pan stamped like that. I assumed it was from the 70s or 80s. The Verichrome Pan has slowed to 50 and the backing paper has printed the numbers onto the film. Haven't tried the PlusX. The film was purchased with a bunch of 35mm HP4 (not HP5) - so I assumed it was all around the same age.

There may be more clues to the mystery when you get to see the backing paper.

Thanks. I will expose it at the lower EI suggested in case it dates back to the 1980's.
I see it will fit on a reel on a Paterson tank:

Here are links to the 2003 and 2005 data sheets, which refer to the film and name changes that happened then - to help with the mystery: https://125px.com/docs/film/kodak/f9-Tri-X_Pan.pdf and https://125px.com/docs/film/kodak/f4017-400TX-2005.pdf

I got some of the same from a friend in just that state. Probably from pro packs with 5 rolls per box. Mine were fine with no special attention needed, but it is all down to storage. A modest increase in exposure and development should not do any harm for a test roll. A low fog developer like HC110 is added insurance with old film. Microdol X or equivalent is very low fog, but does also require an increase in exposure even when fresh; still that was the only developer that made some badly stored early 80's TX 35mm at all usable for me.

I will sometimes shoot a part roll to test and convert the rest to 120 with recycled backing paper. That may be more trouble than most people want to go to, but I hate putting the effort into that many exposures just to see how the film works.
