Can anyone provide the dimensions of the Graflex Graphic View ground glass? I've attached a photo of the rear of the camera in question -- it's a spring back, not a Graflok back.

Steve Hopf thinks that the dimensions may be 100x122mm (3 15/16 x 4 13/16"), but he's not sure. I found another thread stating that the back was 3 7/8 x 4 7/8.

Thanks in advance for any clues.

(I don't have the camera in hand, or else I'd just measure myself.)
