Now that the slant in the wheels has been explained... Dare I even mention that there isn't a single slit in the Speed Graphic's focal plane shutter, but several?
(NOTE: these comments have nothing to do with the slant.)
Right. This is the fun part of that camera's shutter. So, the focal plane shutter consists of a single curtain with several slits. As you wind the key on the side of the camera, the shutter curtain is wound upwards and increasingly smaller slits will pass by as you look through the camera with the back removed. When a certain speed is shown in the window, then when you trip the shutter the slit for that speed is what will be pulled down for the exposure. Now, you can actually trip the shutter again and you'll get a slower speed, since the next larger slit is what's ready to be pulled down next. There's also a high tension / low tension lever which is needed to provide all the speeds.
There's also an "O" (open) speed setting for when you're using the lens shutter. There's a switch which selects which shutter you're using. All this should be on the Graflex web site.
How many ways can you compose? Four: viewfinder, rangefinder, groundglass, wire frame.
How many ways to focus? Four: rangefinder, rail scale, groundglass, beam focus.
I find it's rather limited movements useful.
Quite a camera!
