Not much information on the internet - a little, but not enough, so I thought I'd ask here.
I have a Cooke knuckler, a 12.75" f/4.5 Series II lens, looks exactly like this one (minus the shine):
208655 208656
The soft-focus ring, actuated by using the "knuckles" is stuck. But really stuck.
I need some more leverage, and in order to get that, the middle element needs to be removed so that I don't damage it.
I just don't know how.
Online reports say this element is cemented in there for good. Others say it's cemented but can be removed by soaking in the right solvents.
Does anyone know how to remove the middle element?
Thanks in advance.
