My GAS is out of control, I dig everything on ebay now, what I got is a dirty brass lens in Unicum shutter. It has no name on it, just some labeling on the shutter says, "Bausch&Lomb OPT Co. PAT Jan, 6, 91. Aperture scale starts from F4, but I guess it could be F8 as to modern standard(I don't think this lens was made in 1991, is it 1891?) After a bit cleaning the lens is OK, no fungus or separation, few scratches. What surprised me is the shutter works after the two cylinders got cleaned. One more thing if it's helps to identify what it is, there is a "W.A." label on the aperture scale. Any info would be appreciated. Alex W.
