I picked up a Wolly 8-1/4" Velostigmat with very nice glass cheap because it's missing its shutter speed and aperture dial. I can figure out the aperture marks easily enough, but marking the standard shutter speed marks is a little trickier (I don't have a shutter speed tester). Can anyone with the same lens/shutter tell me the shutter speed marks and approximate distribution (maybe with photo)? I got the "T" and "B" settings fine, and the speeds do get faster in intervals from there. No name on shutter, but I'm sure it's the original standar one that came with this lens.
