I recently got my hands on two of those lenses - they are both pristine on the outside, but one of them has a bit of fungus between the very rear elements. I'm planning on selling the clean one and cleaning & using the other one. The front set of elements comes out easily just by unscrewing it with a spanner tool. The rear element can be unscrewed by rotating the glass, but it only goes to the bottom of the thread and then I can't unscrew it any further.
I'm wondering if anyone knows how to get it out. I could use the lens as is - once I figured out what adapters I need to use it on my Nikon, but I do have access to a clean room lab, UV laminar flow workbench and all sorts of other stuff at work, so when I do have the need for a clean-up I can usually do a pretty good job.... IF I can figure out the disassembly part Smile

Any suggestions would be very welcome.
