It is a box with an open hinged lid. Inside are two reels (paper, I believe, from thumbing through other copies of QST at the bookstore). On one side is a Victrola-type crank. Wires lead out to a set of ear phones and a telegraph key. If I have to venture a guess as to size, judging from the headset and the telegraph key I'd say about 8" high by 10" wide by 8" deep. The reels look to be about an inch or so wide, and maybe three inches in diameter. I assume that winding the crank must have both A) turned the reels and B) generated the electricity to record and play back the signal.)))

"76 Cortland Street, New York City" (((Notice how the ad copy calls it "New," while the 1932 ad says it's been in use for "the last ten years." Also note that it is "loaned" rather than sold, probably because once you learned code, you wouldn't need it anymore.))) Dan Howland (jort@teleport.com) Journal of Ride Theory, P.O.
