I'm hoping someone here will be able to help. I'm stripping down an old pair of Carl Zeiss binoculars and have hit a stone wall with the adjustable eyepieces. Simply cannot see how to dismantle them. Any suggestions other than "send them away"? I work on projectors with lenses, so feel quite confident to strip and clean them if only I could find the magical key to this problem. Will post pics if anyone feels it will help.
