Will do the photo tomorrow (if no-one does one sooner). Remenber that a scale is relative because the aperture is related to the diameter of the f stop as well as the FL. So the gradations betwen stops are the same it's the f no & position that will differ.

You could back calculate very easily and accurately
. The #00 shutter has to be stopped down quite a way before it reaches the f8 max aperture of the 65mm SA.
