I posted a question about a speed graphic not too long ago, and I have another one. How in the heck do you work it. Mine just came in the mail and this one in particular is very very nice, I don't want to mess it up and I am too impatient to wait for the manual. I can usually figure things out but I noticed a few things I hope someone could explain. The back doesn't come off so do you slide the film holder underneath, on the right side if you were holding it to take a photo I figured the top switch must release the focal plane shutter but whats with the lettering and you have to wind it with the top knob. What does the bottom switch do. Last question, how does the ektar lens work and what is the small barrel with the wire coming out of it do? I pushed and the shutter released but i know that can't be the way to take photo's. I'd appreciate any help, thanks.
