Does anyone know if the inserts for the Bronica backs, in particular the GS-1 backs, are interchangeable? I have a 6x7 back with a 120 insert and have located a 220 insert for only $25. Will this 220 insert fit the back and if so would it convert it into a 220 back?
Thanks for the reply. Do you mean "insert" instead of "back"? If I were to put a 220 insert in a 120 back, the counter would still go to 20 (for GS-1)?
