Goerz Berlin Weitwinkel Lynketoskop front element and damaged iris only, focus seems to be some 8". I thought I could try the single element just for fun at least with a packard shutter on my 5x7. I know how to calculate the actual f.stop, what puzzles me is the curious scale engraved on it.. 24-48-182-384-768. Kinda weird huh ? Any hints from someone ?
