I just bought an APO-Symmar 5.6/135 lens in a Copal No. O shutter. When mounting it on a lens board, I noticed a small protruding screw head, about 1/8", that doesn't allow for a flush mount on the board. Is this by design? If so, does it affect the parallel plane of lens to film? Should there be a recessed hole in the lens board? I'm a bit puzzled about this screw since other lenses do not mount the same. Help me out, please? Thanks

First, you really must remove the screw. This is absolutely necessary. Then you may either 1) drill a hole part way through the lens board, allowing the len's f ront assembly to seat properly while catching the screw head to prevent undesire d rotation, or 2) just throw it away. Really. A properly tightened lens shows li ttle or no rotation once it is set to the lensboard, and some slight rotation ha s no effect, anyway. I just toss the screw. Other photographers I know do the sa me.
