<p>There are a ton of repair instructions available through a Google™ search:<br>

whether any of them will help you, you'll have to find out by trial and error.<br>

All of us have at one time or another learned the lesson to photograph and sketch each stage of dis-assembly. This time it was your turn. ;)</p>

<p>Well if you needed a magnifying glass, now you have at least a couple.<br /> Or if you like puzzles, enjoy...</p>

Mario, as far as the glass elements go you may be in luck: job one, find an optical diagram of the FD 55/1.2. If I recall

right, most of the individual elements have a very distinct shape which will help you figure out their proper orientations

and sequencing.

Sorry, I have no help to offer on the diaphragm servicing!
