I have two Empire State Full Plate cameras, both of which require some work. I recently noticed that one has limited rear swing in one direction due to the knob conflicting with the rear focus mechanism. I looked at the other one and it is very similar. I find it hard to believe this was the original design, but I am puzzled. I realize that the Empire State was produced in a few different models. These are not the No.2 models. The one on the right is missing a knob.

Anyone else have one of these? Any ideas?

Thank you.

Cheers,
Clarence
