Among the walkie-talkie cognoscenti, these are a desirable collectible. Made around 1965, these totally tubular transmitters (and receivers... I know, I know...) are all metal, and even have a battery meter to keep tabs on the wallet-draining six AA batts that power the beast. Initially I wondered whether these were intended for kids because they're so well built, but I'm pretty sure that the single channel nature confines these units to backyard adventuring. Though I suppose there could have been a more "advanced" model with more controls... that probably would have required even more batteries.
These rarely come up on Ebay, and when they do they command real bucks. A single unit (so you have to find a collector friend with another one) finished last month on Ebay for nearly $150. The accompanying video was part of the auction listing, and gives a great look at the details of this magnificent spaced-out communicator. Really nice voice on the narrator there... he's clearly into his walkie talkies. Though I suppose it would have been more authentic to deliver his lines over a scratchy walkie-talkie transmission, with a few inscrutable morse-code beeps added in for good measure.
