I have just been given a box of expired x-ray film (Kodak T-Mat G/RA - 18x24cm) so i was going to try using it like normal neg and see what i get.

The only things im trying to figure out is the stocks ISO (for the life of me i can't find it out - i even called Kodak and no one could help me), and how to process it.

Can anyone help me out with these questions?

Thank you,
