Well, I opened up the tin in order to do a clip-test.
Inside was the film, a corrugated card insert and these instructions on a pamphlet:

I hope some of the info above will be useful to someone:
I cut off a length of film about 6" and loaded it into my spiral no problem the film felt OK and travelled into the spiral very easily.
I then prepared the developer and fixer. I used Rodinal at 1:25, pre-wet for 1 min at 20 degrees C then developed for 5 mins with gentle agitaion for first 30 sec then every min thereafter.
It was then fixed for 3 mins in fresh Ilford Fix.
No stop bath was used just a small rinse in water.
After a small final rinse about 5 mins, I opened the tank...
At first I was disappointed as the film looked completely fogged, but as I held it to the light I saw to my surprise there are IMAGES.
Badly fogged either by age or light at sometime (who knows when in the last 60+ years) but there are images of people.
The film is drying as I'm typing this and I'll try to scan and post them later....
But for now here is a copy from DSLR and a Macro lens:

Ghosts...
