I need several metal lensboards for a 4x5 New-Vue camera made by the Newton Phot o Products Co. in the 1940 era. Its not a well known camera. The lensboard is 4x 4 inches and 1/8 inch thick. It has a raised metal ridge on the inside that acts as a light baffle. This raised metal ridge measures 3 5/8x 3 5/8 inch and conta cts the insides of the camera when the lensboard is in place. Does anyone know w here I can find a source for this board or did another manufacturer make a simil ar metal board with the same specs? Contact: talltandj@aol.com
