Just a little note for others. I brought in one of these today in need of cleaning. My first take-apart on this lens and it went really smoothly.

I rate this lens easy to work on. Only minor problem was removal of lens ring writing with sticky back. Next time I'll warm it a bit first.

But overall I was really surprised regarding ready access to the first several lenses and lens groups. I did not take apart the rear of the lens, but I did drill all the way down to the aperture (front).

The tricky bit is to built together the lenses without creating a de-centered orientation of some elements.
