Just purchased on ebay a Kodak Ektar 203mm f7.7 lens in Flash Supermatic Shutter. Paid no attention to the lens board or shutter. I plan to put this on a Crown Graphic and thought I'd just buy a lens board for it, but I stupidly did not focus on the fact that lens boards are both camera and shutter specific. Any suggestions (if the board it comes on doesn't fit a Crown Graphic). Lens won't arrive for about a week.
