Thanks for the ideas but I don't think its Fomapan. I don't think I've ever shot any, plus it looks like a "lick and seal" tab. I think its either Adox or Freestyle's house brand, Arista? I don't know, I do like to try different films so perhaps I did have some Fomapan and just don't remember... I have this and a couple rolls of Ilford to develop so I guess I'll do the Ilford first and then try Mike's idea and hope the other end of the backing paper says something more.
