Didn't work on this film .

The test procedure was;

Presoak for ~1 min
K ferricyanide 50 g/l for ~10 min
Wash with running water for ~3 min
Re-develop with Rodinal (1+10 for ~2 min) (Because ferricyanide bleaches the optical (silver) sound track away.)
Wash with running water for ~5 min
Stabilize with Jobo "3-bath E6 stabilizer" (with formalin), double strength for ~2 min.
This process that was suggested was provided as a shot in the dark [pun intended] to save the transparency.
