The Nocta is described pretty well in Oosten's "The Ultimate Asahi Pentax Screw Mount Guide 1952-1977," pgs 255-256. From the three pictures in this book, it appears as though the eBay lens is complete minus the larger focusing handle. A rare unit indeed.
The description of lens from the book:
"The lens is a highly specialized Takumar 1:3.3/300mm for Infrared photography. The minimum aperture is f/22, the angle of view is 8 degrees. It was supplied with a 256X Neutral Density filter (42mm) for use under daylight conditions. The actual front of the lens measures 300/3.3 = 91mm in diameter of which only the central part is used in daylight." - pg 255.
