Kodak Commercial Ektar 12" 305mm F6.3 in Acme Syncro #4 shutter (COATED) Glass is in great shape with a couple of tiny bubbles from manufacturing which is normal for lenses of this age. F stop adjustments are smooth. Includes mounting ring and box. There is a crack in the top of box. See photo. The shutter works at all speeds and sounds good but at its age it more then likely needs a cleaning.
