I was wandering though an antique store recently and came across some beat-up brass lenses (which I bought). When the owner knew my interest, he went upstairs and came down with a variety of other LF-related items. I don't know much about them, but happily bought them (for too much money), seduced by gleaming brass. When I dragged the lenses home and started looking at them closely I realized I might have wasted my money, as the glass on most seem to have problems, and one is missing an element. Here they are.
About 90mm f4 and 180 f8 with the front element removed. Seems to cover 5x7, no diaphragm or provision for stops. What is it? Is it a camera lens or something else? Any idea of age?
Unmarked Petzval. I checked to see if the elements would unscrew, but was in a dark shop and bought it without really checking it out. Big mistake, as when I got it home I realized it would not create an image. I pulled it apart and then realized it was missing the rear air-spaced element. Not sure what I can do with it now, unless I can find someone with an extra 2 5/8 in diameter rear element. I can get an image with the front element alone, so at least I could make a meniscus lens.
Fujinar-SC 1:4.7 25cm 132277 in a well-functioning Copal 3. The lens elements have numerous cleaning wisps and the internal elements look dirty, but I cannot figure out how to disassemble those (if its even possible).
