Beseler lists 2 6x9 carriers for the Beseler 45:
#8314.....2¼ x 3¼ roll film negative
#8315.....2¼ x 3¼ sheet film negative
Does anyone know what the actual opening size of either of these? I could measure film (and will if I need to) but I figure Beseler must have put some thought into the opening size.
I plan to file out a 6x6 carrier for 6x9; using a dremel for most of the metal removal and then a file clean up edges and corners. Not sure yet how I'll blacken the newly cut edges.
