I've got one---a beautiful lens that serves as the "really really" wide on the 'dorff. I've been told or read that it is a tessar design, though I've also been told or read that it is a dagor design. Kingslake dosen't really get into it in his book(the one I have, anyway) so I was wondering if anyone of you could tell me what kind of lens my Wolly actually is? Thanks!

Ir's a rather elaborate design, eight elements in four groups of two elements each. The design intent was not to gain additional coverage over the more common f12.5, just a gain in speed. The added elements would have given the designer opportunity for better corrections also. To what extent this may have been realized, I don't know. The lens was made long before coating, however since it has eight air to glass surfaces, coating was a major improvement.
My source is the "Wollensak Lens and Shutter Guide".
On the Wisner website, it is indicated that the Wolly extreme wide angles are from the "Gauss" family of lens designs. I think that makes it more Dagor-like than Tessar-like. At any rate, a great light weight 8x10 wide angle.
