Chris- I once had a Wollensak enlarging lens. It was probably close to 40 years ago, so my memory of it may be a bit hazy. If memory serves, however, I found it to be a little less contrasty than my "good" lenses. I gave it away, but wish I hadn't. Since rediscovering my plastic cameras, a few years ago, I'd like to see how it would work with those negatives.
