[LargeFormat] Wollensak Studio Shutter

[Richard Knoppow]

  Does anyone on the list have a lens in a Wollensak Studio 
Shutter? If so, does it have any patent numbers on it, I 
would like to have them. I suspect that its old enough to 
have only a patent date but not the actual number or 
numbers. I am trying to find out more about how these things 
are acutally constructed.
