I have one of these which I am not using, and would be happy to sell. It is
a Keystone Visual Survey Telebinocular, Model 46B.  It is in excellent
condition except for slight cosmetic imperfections in the base.  Comes with
a case (fair condition) and test booklet and a few test views. (The test
booklet is in poor shape.) I'd like to get $150 plus shipping for it.
