> Might you know of someone who would like to have a military surplus radio beam filter, NAF 68304?  They were used in air navigation, I think primarily as part of a system to aid aircraft in getting a heading to a landing field.  I have one in nearly new condition and would be glad to send it to someone who would truly like to have it just for the cost of shipping.
