In 1943, teen girls went for the boys on the Audio-Visual crew, as shown by this illustration from the October 1943 issue of Popular Mechanics.  (Note the book bag at her feet, ready to be carried home by one or both of the helpful lads.)

The two shown here are running wire to an extension speaker using the large diameter reel shown in the magazine. Not only are they impressing the girl with their knowledge and skill, but they’re being patriotic by being careful with wartime strategic materials, since storing the cable on such a reel made it last longer than if simply hung on a nail or small diameter peg.

The boys probably made the reel in wood shop where they showed their skill, since the magazine noted that the unusual design, shown here, “provides an interesting sawing problem for students.”
