In 1952, when I was 9 or 10 (depending on when I was given the book) I
received a 1952 ARRL Radio Amateur's Handbook from a friend of Dad's. That
led to an amateur radio license a few years later and, much later, to a career
in engineering.

I still have the old book and, over the years, I've used it a lot, even though
I now have multiple editions scattered from 1926 to 2018, but I've mostly
ignored the catalog section in the back. Looking it over recently, I found
that the various pages in the Hallicrafters section carry the image of a slide
rule, probably a K&E with the scale set (duplex but with one side shown only):

K A / B T ST S / D DI

The image (drawn, not a photo) is vertically oriented, about 9 inches in
length on the 6 1/2 x 9 1/2 inch page on the right hand edge of each page that
includes pictures of Hallicrafters receivers or transmitters.
