I note you used your own measurements on the Folmer Graflex/Kodak. I
wonder if the disparity is wear (mine show a noticeable amount) or a
different series.

Actually, looking over the chart, it seems that all the empirical
measurements agree pretty closely. The only disparity seems to be
between the "standard" for exposure height (7.010"), and the actual
openings, which are all 6.75.

Easy to allow for this: I'll simply make the exposure opening in my back
the size of the "standard". No harm, no foul. (I'll make the ground
glass larger as well, but mark the actual exposure opening in pencil on
the GG.)
