I just picked up this camera on ebay. My first Graphic. Can anyone ID the model and which flash should I be looking for as the bracket is not the "normal" one you see on most graphics. And what is the screw for on top?

Your camera is an Anniversary Speed Graphic that has had a few updates done to it. The original "Graphic" spring back has been replaced with a "Graflok" back. This is a good thing since you will be able to use many more types of film holders with the Graflok. The viewfinder and rangefinder have been updated with later-style replacements, probably from a Pacemaker Graphic. The flash bracket was made by Heiland and will work with many types of flash handles. You will need to find a set of the Heiland ring-type clamps that work with this bracket. I will post a picture if I can find one.

This is what the Heiland flash clamps look like. I found this picture online.

thank you. This info helps a ton!
