One of these is the conical rubber grip shown in the pic. I am wondering if a small shot of WD40 on the internals of the eyecups and then the outside of the summit of the cone stuffed up the internal diameter of the eyecup might give you sufficient grip to unjam the eyecups.If you would need to internet order these then you might be better off asking Zeiss to send some more eyecups.One last thing. have you tried running hot water over them? Expansion caused by this can often unlock stuff that is stuck. If it works then dry them with a cloth and leave them near but not on a radiator in the extended position and when dry give the internal surfaces a small finger-tip's worth of light grease.Good luck with this one.Lee</blockquote>
