  During WW2, Weston supplied the US Navy with Radio Receiver Analyzing Equipment models OE-6 and OE-8 through OE-12.  All of these Navy models contained the Weston 664, Weston 665, test leads, and assorted tube extender sockets (to simplify testing of live circuits), all packaged in a wooden box.  All Navy OE models were identical except for additional new tube data added for the later models.
