Anyone know the lensboard size for a 12x20 Folmer & Schwing camera? I am taking a look at one tomorrow in hopes of eventually buying it and would like to mount my 355mm G Claron on a lensboard to take a look at the image on the GG. I have a 7x17 F&S and hope the 12x20 takes the same size... but it looks as though its a bigger lens board from the photos Ive seen. Did a search on here and through google and didnt find much. Thanks in advance.
