1960's? Coinalyzer From Borst Engineering

Approx 12 x 5 inches with a well executed light wooden case. The included instruction sheet describes this machine best: The "Coinalyzer" is an automatic, electrically operated machine designed for the purpose of viewing and sorting large number of coins, easily and speedily. Both sides are visible at the same time, magnified and non-reversed. We've never seen or heard of another example of this exact unit, though there are some similar machines we did notice in our search. It appears that one tube is missing, but we believe the machine to be in working order. Sort away!
