Big brass beast. No aperture or focal length markings.
Rear glass diameter is right at 3 inches.
Uses Waterhouse stops, but none included.
Can you make your own stop plates out of metal or plastic?
I'd assume you could start with a nominal diameter and measure a
constant light source with an incident meter on the ground glass and
then work up a bunch of plates for any stop you may want.
