I looked at the shutters on the Packard site and am either partially confused or thoroughly not entirely sure about how they work. It SEEMS that one can get either B or T type timed (#5) or that plus instantaneous (1/125 s) exposure (#6) but not the usual Copal type speed variety? Nice that they go up to 8" indiameter - I guess one could machine adapters to fit most barrel lenses? What is the Syncro shutter?
Thanks for any help!
