ASA and DIN were superseded by ISO in the mid 1980's around the same time as DX codes on film cassettes and negs was introduced. That would put your film nearer to 30 years old.
They still make Tri-X that you can buy and use. If you have never exposed or processed B&W before, you can use your old roll of film to practice loading a film processing reel.
Better yet: get an expired film (any brand) for $1 to practice with and use the Tri-X for shooting.

To shoot it at 100 ASA is a good idea, as has been stated before.
I recommend to process it using "Stand development" after that...
Someone posted in another thread that the best thing to use for really old film is d-76. I remember Simon from Ilford agreed but don't remember all the details. Maybe someone else can refresh my memory.

If it has a short (current) leader on it it is post 72 long leader pre but forgotten when they changed exactly.
Id stick it on eBay people will pay for nostalgia more valuable if you have tub and pack.
if you wanna try load and shoot one frame rewind cut and soup in ID11 with added KBr and BZT.
Id not bother normally lots of fog.

I agree....if you're just wanting a film to use to take pictures (as against any particular interest in experimenting with old films), I'd put this one on Ebay as a collectors items, and use the proceeds to buy a fresh film. Old films are becoming very collectable.

In the dark, cut off about two inches of UNexposed film and place it on the film aperture of your camera (of course, in the dark). Shoot a scene with much variety of tones at EI 100. Process normally. Wash and dry. Now, with a magnifying glass and a white piece of paper behind it, scrutinize the negative carefully to observe both shadow detail and highlight rendition, as well as general contrast. You can make your final analysis for the film doing this.
About ten years ago I bought two 100 ft rolls of Tri-X that 'expired' in 1958. Its current speed is about EI 32 and fog is surprisingly manageable. It is amazing how good some really old B&W film can be. It's just that too many (most) simply guess and shoot the whole roll and then are disappointed. - David Lyga
