I have a Century Graphic 23 with a Kodak Ektar 101mm f4.5 lens in a Kodak Flash Supermatic shutter. I have never liked this shutter since I worked on them at National Camera in 1973. Like mine, most of them are flat worn out and erratic, no matter what you do to them! I'm looking at a Wollensak Raptor 101mm f4.5 in a Graphic shutter on eBay with a very scratched front element. I'm hoping and need to know if my Ektar, front and rear groups, will fit in this shutter in place of the wollensak?? My Ektar front group has 29.5mm thread. Does any one have information on this? Much appreciated!
