Hi, I've just bought a c.1908 Goerz Ango camera, with the wonderful Anschütz focal plane shutter. Although most of the complex set of dials & buttons to operate the shutter could be guessed, anybody knows where I could find a manual of this camera, or even better, a video of the way to use it? I could be even more important to know if there's any dangerous setting to avoid (like speed setting BEFORE cocking the shutter in soviet Leica copies). Thanks in advance. I'll post pictures of the camera when I'll have it in a couple of weeks.
