Yup, never was an option.
Best bet is probably Tri-x or Neopan 400 pushed hard. But, you're never going to get the same look. That was a unique film. Delta 3200 is a soulless beast. Great on a practical level, if you want 120 and need the speed. Flat, dull, and has mushy grain. Good in XTOL if you're looking for a smooth look with minimal grain and good speed. But, I'd rather have Kodak P3200 in 120 any day.
