My K&E Cooke Radio (version of a Polyphase Duplex Decitrig) sits in its leather case on my desk. I have the original manuals as well. Bought it new from the K&E store in NYC and used while in USCG in ‘70’s and taught at the Electronics Training Center. Marvelous how the batteries are lifetime guaranteed, furthermore the battery “self resurrects” when the rule is passed along to a descendent. My 35 YO son is better with it than I am, but he prefers his circular rule.
