[Milsurplus] What is this thing??

Nothing else, just a large simple
rotary switch.  The whole box is more
or less transparent to the loop wires
that go through it.  In a normal range
installation the switch box was hung
on the wall behind the two transmitters.
There may have been an SCR or SCS or
something for the four-course loop radio
range.  It came with two range transmitters,
E-W and N-S wire loops on 50' poles outside,
two "Z" Marker transmitters, a gasoline
powered AC generator.  All in a pre-fab wood
building with the "Z" Marker antenna on the
roof.  Ample living space for a couple of
troops and their dog, or visitors.  I have
a couple of pictures, but I don't know
if the switch box shows in any of them.
