I find it fascinating that it has 6 receptacles, exactly the same number as modern power strips. Home- or shop-built, but par for the course in an era when electricians frequently built panelboards on site. Ditto the exposed live parts, no big deal back then. Safety was equated with common sense; no one thought much of those times when you are busy with something and take two steps backward without looking.
Of course fused neutrals were not prohibited back then; they were required!
I wonder what kind of cord cap this had?
