Hi,
I have a Meyer Optics Telemegor 250mm silver type lens which needs some cleaning.
I saw in a thread that someone suggested unscrewing the middle section right above the focusing ring.
In my case this is so tight that I can't unscrew it or it is currently blocked by something, do you have any suggestion to do it?
Looking at the lens, there is a little screw (green arrow in pic) below the aperture ring, I have a doubt is it related to the aperture blades or it blocks the section?
  
Thanks in advance for any suggestion
BR
Giorgio
