Yes, R09 is to be considered an Orwo product, although it actually was produced by Calbe and still is. Rumours are that R09 is the old Rodinal formula, while Agfa Rodinal is slightlly changed. As I'm still busy with my Agfa Rodinal, I had no chance to test the Foma R09 I picked up some years ago in Praha.
