    I have a Rodenstock Ysarex 127mm f4.7 in a Prontor SVS shutter. I want to remove the lens rear and front cells (glasses) from the shutter. I was able to unscrew the rear cell, but I have no clue how to unscrew the front cell. No threads visible, no notches, no screws... I tried unscrewing it using pressure with my fingers but it doesn't move.

    Any idea?

    thanks

    That's something I have also tried to do in the past with no success. I will be interested in the method too.

    Thanks for the link.

    I'm tempted to leave mine alone as it works fine at all speeds except half and one second but I'm still interested in learning how it comes apart as I couldn't work it out myself.
