3rd time lucky!
Joe, this is the third and last time! 😀
All Leica lenses I have taken apart showed me Leica made them to be easily maintainable. With a minimum of equipment you can get a really long way.
1. Loosen the tiny screw in the chrome barrel. This one fixes the lenshead in the barrel. Mark the position of the lenshead relative to the barrel first. The thread that holds the lenshead is very fine.
2. Unscrew the lenshead. This part is easy.
3. Take the spanners and unscrew the rear retaining ring that holds the rear glass. I unscrewed the last time with a knife right across because it did not come close to the glass. (or was that with an Elmarit?).
4. More difficult. The glass parts are in a brass ring that fits really tight. You can shake or shock these out. Careful, you have to catch them on something clean and soft. Somewhere in between is a thin black metal ring. Remember where to put it back later!
5. Now you get to the aperture blades.
6. Clean where necessary, let it all dry and put it all back together.
good luck!
