i know this is a long shot, but does anyone have a schematic or exploded parts diagram for the Rolleikin counter accessory that goes on the 3.5 Rolleiflexes and Rolleicord V cameras? I have one that appears to have been tampered with... And at least one part was not replaced. The frames do not increment when the button is pressed. Any help will be sincerely appreciated.
shutterfinger... as it ends up, that document identifies the counter knob as a unit piece-part on the Rolleiflex 2.8E. The earlier exploded diagrams, Rolleiflex 2.8B, shows the counter knob exploded into its component pieces. Now wish me luck as I try to repair the tampered counter knob I have.
I'm not familiar with Rolleicord/Rolleiflex cameras but I'm very good to excellent at reading/writing repair manuals and following exploded diagrams so it seemed like a good hunch to mention the manual after scanning (as in quick look/reading; reference the annoying popup about that electronic recording system being banned on this site) over the diagrams of the cameras you listed. Its good to hear you found a diagram to work from. One thing I noticed looking through the manual exploring a solution to other problems in the past is the similarity between the models.
Butkus has various exploded drawings and manuals of Rolleiflexes on his site. You need to send him an email requesting particular ones if they aren't available directly from his site and he will send it to you; this is made clear when you try to view the drawing or link. For example, I have the 2.8C exploded diagram and it gives a back side view of the Rolleikin counter exploded out.
Please drop him a few dollars if you use his site. It's an amazing resource. I hope that it is mirrored somewhere.
