At Goshen, I mentioned that I had seen some vintage flight calculators at a local store. went back this week and bought them, although the electronic one was no longer there. The two approx 10" devices are:
C1 Flight Computer marked 1972 by Aerodyne Inc.

Dalton E-6B Computer, also marked STIFFLER AERONAUTICAL INSTITUTE. It has a 17 page instruction booklet.
There is one vinyl pouch that fits either device.

Anybody interested in them?
