$190 seems to me a pretty good price, I paid over $300 to get one of these a couple of years ago and recent sales I've seen have been over $200. I recall one on the Large Format Photography Forum for about $250.
This appears to be in a standard Copal 0 (not 00) shutter like the one I have. Schneider's 1963 literature shows this lens in a size 00 shutter, but their 1967 brochure has it in a size 0. This lens' serial number places its manufacture well after that, so I believe it's really in a Copal 0. That's a big plus, it's basically a standard modern-ish shutter, and easily maintained.
One nice thing about the f/8 75mm Super-Angulon is that it takes 49mm filters, smaller than any of the modern 75s. It allows me to step up to 52mm, the size upon which I've standardized for my "walking around" lenses. Coverage is tighter on 4x5 than the bigger faster WAs, so it's not well suited for architectural work, and I've found it to be a little softer in the corners, but it's hard to argue with the size and, especially, the price.
