I had a discussion with Frank about this off the board and he suggested I run it by the board.
Attached is a photo of the fine focus knob of my 5x7 Norma's front standard. The rear standard is identical. As you can see there is no locking knob.
In Philip Morgan's Norma CLA video, which I closely followed, he mentions some did not have fine focus knobs but I find that hard to believe.
Frank suggests it may be a user modification.
Either way I don't like it. It's difficult to unlock shift or swing without altering focus.
