I acquired a Schneider Super Angulon 65mm F8 lens for my Crown Graphic. There i s severe vignetting on the ground glass for which the seller of the lens has inf ormed me that I need a recessed lensboard.

Is anyone familiar with this? A recessed lensboard for the Graflex? When focus ed at infinite, the rear element is already <1" from the ground glass.

Thanks for any help.
