Does anyone know where (worldwide) I can find the Rollei CM 77/30 interconnectable magazines or similar, for the Rolleivision 66 Dual-P slide projector? My current supplier stopped selling them, so I'm desperate to find a new source! I want magazines that go directly into the projector. There exists slide storage boxes with which it's necessary to shift all the slides over to a real magazine for viewing in the projector. This is not what I'm looking for. Any ideas would be greatly appreciated!
