My favorite project was the Wide Angle Telescope - Camera constructed with the lens from a K-22 Aerial Camera Lens Cone with a Tessor Optical System, f/6, 24" focal length. The cost of this lens was (Used $39.50) (New $59.50) at Edmund Scientific. It stated that this lens cost the U.S. Government $1200, and we talk about the cost of government hammers today. That would be about 10 times that amount in today's dollars. Of coarse that was way out of my reach even at the used price! But I did look at those pages over and over. They even had one of these Lens Cones at the local Army Surplus Store where I lingered many times looking at it from all directions.
Just looking at these pages again makes me want to see if that K-22 is still available on the net.
