Cyberjunkie is correct. The Super Graphic does not have a focal plane shutter.
Prof_Pixel is also correct about the two versions, Super Graphic versus Super Speed Graphic.
A very good friend of mine has the Super Speed Graphic and I have been trying to trade him out of it. I posted a question about it on Large Format Photography Forum and learned that even new the Super Speed Graphic could not reach the claimed 1/1000 of a second shutter speed, more like 1/700th. Also the shutter is not very reliable.
What I like about the Super Graphic is that it is a metal camera and it has a rotating back. Of course these features are not important to everyone.
Just a little information that I recently learned.
