Film fog - cassette info

[George Collier]

After a trip, I started processing film, all Trix, 35mm, in HC110 (1:60).
I hadn't used HC110 for a while, so I first developed a single roll of 36 exp, all good.
Yesterday I developed 2 more rolls, one 36 exp, one 24. The 24 came out normal, the 36 is very and uniformly fogged, maybe a stop or two, almost a never for me, unless the film is out of date.

I bought some film last year, and used the last roll on this trip (a 36). The other 2 rolls were purchased just before the trip, both orders by mail order from a well known source.
The boxes were trashed during the trip and not retrievable. I had thrown all three cassettes in the darkroom trash, and pulled them out after seeing and washing the film yesterday.
Attached is an image of the three. I don't really know which 36 (2 of them) was the fogged roll, but I noticed the difference in the graphics on the cassettes for the first time, and no cassettes are left of the last year order (except the one here).
The cassettes are resting on the film trap, with a bar code and numeric code on the other side. The numbers in front of each cassette are the numbers on that cassette.
Does anyone know -
When did the cassette ink color change?
And what do the numbers mean?
Obviously the boxes would be good to have, but I don't.
On both orders, Trix was difficult to get and I had to wait for supplies to be replenished.

110294 is the current number for Tri-X 36 exposures. I just bought 20 rolls last week with experation date of March 2024.

Thanks for that - so the 010294 is for 36, but maybe a different period?
Also, I'm just now scanning the printfile pages to make "contacts", and the fogged film has much more arch curve to it, across the film.

From just poking around on the internet, it looks like 010294 was the previous product number. The current box has changed the graphics slightly. The previous box had Kodak Professional Printed above the 400TX on the side of the box multi language description below. Now it's marked Tri-X 400 Film over the 400TX with Black & White Film and Kodak Professional below. The multi language has been moved to the end flap. It could be the packaging changed at the same time the single use Tri-X camera was introduced.

the one with 400 400 400 is from a couple of years ago now.

In June 2021 Kodak had to temporarily switch to silver end caps, due to a worldwide shortage of tin free steel. I don't know whether that situation is still current.

Discussing the lot of the cassette not necessarily takes us to the cause of the fogging.

The OP's emphasis on the cassette, not the lot, made me think of a light leak issue at the cassette. Now I am not sure about it.

Thus, what kind of fogging this is about?

FWIW. I have recently shot and developed several 010294 rolls with expiry date in 2012.

They had been keept in room temp (fairly constant around 25°C) I developed them in HC110 1+50 and they came out fine without fogging.

I don't normally shoot TX so I don't know when the change to 110294 happened.

The green number 400 contained old or even expired film.

The green number 400 contained old or even expired film.

My first thought too--though Tri-X properly stored usually lasts well past the expiration date. Maybe the one roll was heat-damaged?

The fog is, as stated in the first post, uniform and total on the roll. The aggressive curl leads me to believe that this is a random roll, from my own stock, maybe I didn't notice that I had in a camera bag and used by mistake. I can't imagine a supplier shipping 8 rolls of film, all fresh except one.
