I recently purchased an 8 x 10 Century Camera #7, for display. (I have 4 x 5s for actual use.) The lens with the camera is a Bausch & Lomb Series 1c, f4.5, no focal length stated, but it says 8 x 10, and says 1903, which sounds roughly correct, but perhaps a little early for this lens. There is a Packard shutter, air bulb operated. The lens has a normal looking aperture adjustment ring, with modern f stops -- f4.5, 5.6, 8, 11, etc. But there are no aperture control leaves in the lens. It is siimply wide open.
The control ring is frozen at f4.5. The date of the lens roughly matches the date of the camera.
My question concerns the aperture controls. Would such a lens in stock condition have internal aperture adjustments? Would they be measured in modern f stops? If not, did this lens use Waterhouse controls? Since I have no plans to actually use the camera, I am not concerned operationally. I am restoring the camera and would simply like the information.
Any information would be appreciated.
