I have a 210mm Wollensak Raptar f4.5 lens in and Alphax shutter that has "US Navy" on it. The shutter has no f stop markings on it and I was curious as to why this is so. I've marked f stops on it using the aperture diameters of another 210mm lens, but I'm interested in selling the lens, and when I list it, would like to have a reason for this anomaly. Also, is the way that I figured the f stops legitimate?
