I would like to remind everyone that Dmtry comes from the Ukraine, where English is not the first language. So, Dmtry, about Graflex's---Anniversary and earlier come as Speed Graphics with 2 shutters. One in the lens, and a focal plane shutter in the back. Pacemaker Graphics were made both as Speeds, with the two shutters, and as a Crown with just the front shutter. The next model was the Super Graphics and they do not have focal plane shutters. For your use, you have to decide if the ability to use Russian lenses that have no shutters is an advantage for you.
