All, I have decided to scrap my electro-mechanically actuated packard in favor of a #5 shutter on my DIY lens project...For two basic reasons. #1 weight savings - no battery pack, no solenoid, no big board to carry around. Plus, I won't have to carry around a bunch of different f/stops. #2 - simplicity. This speaks for itself. However, as you all know, these things are HARD to find. So my first question is this - anyone out there have one for sale ??? My second question is - if you have one that isn't for sale, who would be willing to take measurements of it for me, so at least I can cut my lens barrel to fit. This way, at least I can make a dummy spacer for the shutter, and have my new lens barrel functional while I wait to find and install the shutter. Thanks !
