I can’t accept that requirement because no meterless M42 exist with the lathe cut. So for me no SL. The SL would be my choice. Maybe.. I could swap out the mount.
I have both the Spotmatic F and the SL and I think you can't swap the mounts. The mount on the F has 4 screws on the front, the SL mount is completely flat so it is probably mounted from the backside. From that I guess the backsides of both mounts are also different.
Where is that other thread you mention in post #133 Bill?
Edit - Never mind, I already found it.
