Well, I did some careful measurements, and if I remove the two-inch short mount, I have just enough room to fit in an adapter for the Kilfittscope in Nikon/Contax mount (thread in front, bayonet in rear), and achieve infinity focus. It will be a tight fit. Will let everyone know if it works. If it does work, a Visoflex I should work as well, since it requires 2 millimeters less space.
Fred: Thanks for the pictures. Yours is similar to the TV Nikkor I found on-line on Montana. Both have the same black beauty rings. Different serial number series. But what is the lens mount? WES
