FWIW, the Super Speed Graphic is the only Graphic with Speed in the name that doesn't have a focal plane shutter in the back. It was called Speed because the lens that came with it was mounted in a shutter with 1/1000 top shutter speed. Those shutters invariably self-destruct after a few months of use and can't be repaired due to lack of replacement parts. I still much prefer the Crown series due to lighter weight. There are plenty of lenses in shutters available. Bob
