My FK 13x18 came with a shutter as well - though not as cool looking as that one. Yes, you can shoot landscape or portrait - the one shown is set for vertical - the entire back can be mounted either way, the little chrome clips that you can just see at the top edge of the back are what allows that. The ground glass flips up (or to the side, depending on format), which was a bit confusing at first, but actually makes a lot of sense. These were designed as plate cameras and it looks like the one you are eyeing comes with a plate holder (the seller calling it a cassette). The missing ground glass should not be a problem to fashion yourself. The ground glass goes in a frame that is hinged to the back - the screw holes for the hinges can be seen in the fifth image.
