Now that's a kit that will attract attention anywhere. Operates on city 110-volt power lines. Shipping weight of 100 pounds, and purchase price of $51.00 (a lot of money in those days). You needed to be serious about your interests.
Published in the 1917 Sears-Roebuck electrical experimenter's / radio catalog (an early one, indeed).
