Does anyone have the information on the image circle of a 600mm Rodenstock Apo Ronar lens? I am not sure of the year of manufacture, but am trying to find out in general if this lens would work on a 7x17, 8x20 or 12x20 at infinity focus.

An older Rodenstock brochure I have lists the coverage of the 600 mm f9 Apo-Ronar as 43 degrees, 476 mm at aperture f11; 45 degrees, 496 mm at f22. These are for reproduction ratio 1:infinity.
