Super angulon 90mm F8 will not focus?

Ian, are you saying there is a section missing on the left one? I am not certain, as i have seen rear cells come apart right at that spot, but do not have threads that fit a shutter of any size... This fits directly into a #0, so i am just guessing it is fully assembled. The sealer black paint and lacquer looks intact as does the face of the rear element.

With that said, i did see on occasion in the past SA with rear cells that looked just like this and lenses worked fine. That is, they looked like that on the outside and rear end, as i did not pay that much attention to the inside part of the rear cell.

No, I'm saying look at the rear metal barrel, the SA's are conical then a straight bit holding the rear elements, your barrel in the 1st & 2nd images has a step in that barrel and it's rather obvious.

Yes i see that now. So - alas, can anyone identify/place the cell on the right?

Ian - just came across this random newer SA 90mm - rear cell actually looks exactly the same as the bad one i have... with the step at the bottom.

Well spotted, it's clearly different to the other 90mm f8 SA rear cell so perhaps Schneider re-designed and changed the lens at some point and an older front cell is incompatible with a newer rear cell.
