The Yashica Minister III article states - "The iris comes off as a complete module. First unscrew the lens rear element. Then just remove two countersunk and one pillar screw. You will need to remove the brass cotter from the shutter release shaft but the cotter of the shutter-cocking shaft can remain. Do NOT - repeat NOT remove either of the circlips on these shafts. In particular, removal of the shutter release shaft circlip will make lots of extra work because the shaft will then drop and the shutter release interface with the self-timer beneath, will displace. You would then have to dismantle the lensblock from the front to access the escapements,remove the timer escapement, reposition the shutter release fork, fit the circlip - and reinstall the self timer escapement. You have been warned ;-)" The Iris module on my Minister could not be removed without removing the shutter release shaft circlip, there is a brass sleeve inset in the body of the iris module that prevents this. So the procedure described gets hairy quickly once you've followed along to that point.My shutter had only five blades, it may have been constructed differently than the one in the article, or not. Hopefully this will help someone!
