Decided to take the aperture scale off the 210mm f9 Kowa Graphic's Copal# 1, put the scale in scanner.
This 210mm f9 Kowa Graphic was once owned by Morley Baer. He used it (8x10) for a LOT of years before his estate put it up for sale and how it ended up here. Not exactly sure where this scale came from, but it has been accurate enough for Morley and every time I've used this lens.

The machinist scale end upside down and the hole with the screw mark serves to locate the reference point of the scale when applied to a Copal# 1 shutter.
