Sorry I can't specifically answer your question. My enlarger came with a Wollensak along with two or three other lenses. They were not in any kind of condition that I would use so I just got the El Nikkor and the Schneider. If it was a mint copy I would have given it a try just for fun. OCD though would have forced me to at least try and do a head to head comparison with a late model Schneider.
