CAY-46077, part of an RBM-4 installation. The service
records were kept on
a sheet of paper attached to the inside of the top access lid. Made by
Westinghouse.
Nice provenance. The RBM-4 was used by the Marine Corps as an advance
medium power radio station for things like beach landings. The transmitter
is a TBW-4, and together they make an MM-4, the complete set.
I would bet that only ten or so MMs saw use in any landing, perhaps even
less. Your radio probably handled some VERY important traffic.
More info offlist if you want.
