Old Angenieux disassembly - need help

I've got an Angenieux 135/2.5 lens in Exakta mount, very nice one... Unfortunately, it has some internal haze and I can't figure out how to disassemble it for cleaning. There are no screws on the rear mount or the barrel. I wonder if anyone here knows a secret how to start dismantling it?

Generic advice: most lenses do come apart from the front of the lens, first you take off the nameplate. The screws under focusing rubber / ring are usually for focus adjustment, don't touch them unless you know what you are doing.

Looks like there is a tiny screw that locks the front ring (picture 3). After that you are on your own. Smile

Oh yes, thanks! I have removed this screw and was able to unscrew the front element. And that was it. The next one did not have any ring with grooves to apply the spanner wrench to and nothing that my rubbber tools could grip well enough.

But it seems that you may be right, the path to the back for this lens is through the front. I got used to other lenses where you dismantle front and back independently, meeting in the middle.

Please I have the same lens but with an m-42 mount, I have removed the first two lenses but I cannot access the iris and the helical to solve a gravel gap in the focus system I have removed the diaphragm ring but the lens does not open, the back has some samples in what looks like a huge retaining ring but that one does not move, please someone has more information
