My local camera repair friend, Michael at Kiwi Camera in Winter Park FL, says there is nothing special about a Zeiss Ikon. He says any competent camera guy should be able to do just about anything needed. Mine was the first he saw and he aligned the RF in about 5 minutes. I also had the iso / shutter speed knob reattached when the screws came loose by a local camera repair guy in Pensacola FL. (I was passing through town) He had never seen one either but said everything was very common.
Some of the electronics seem to be shared with the Nikon FM 10. I think, but am not positive, this includes the shutter.
I don't understand why everyone believes they have to send their cameras around the world for common things. There is probably a local camera repair guy around if you live in any metro area. They don't advertise, just stay busy catering to the local pros.
