lens help needed

Hi everyone,

I got last week from ebay a Voigtl�nder f2.8 135mm (which seems to be the same as a Rolleinar MC 1:2,8/135mm), and their aperture blades are not working.

In order to reach them, I tried to disassemble the whole lens, but now I'm kind of stuck trying to take apart the last "tube" that holds the front lens and the aperture blade assembly. There are no more apparent screws, only a front ring that doesn't seem to be screwed inside as most other lenses are, and one "junction line" between the front "tube" that looks like it could unscrew (but applying a lot of force hasn't helped at all). Anyone knows if this front assembly is glued together? Would be possible to force them apart, or heat it to unglue it, if it's the case?

The front "ring" can be seen here (the metal part in front of the lens, behind the filter threads):

Trying to unscrew it was also pointless, didn't manage to make it move.

I'll get some more pictures later to post here...

Thanks a lot for any help!

I edited one in... but the system does not take it (??)

I just tried and it seemed to work? There may be still a few bugs in the forum system perhaps.
