>> I count five crystal filters made by NETCOM, center frequency is 5.2 MHz. There is an empty spot for a sixth filter but the front panel has only 4 push buttons to select filters which are labeled VNAR, NAR, INTR, LSB (very narrow, narrow, intermediate and LSB. If no push botton is pressed the USB filter is selected.

>> According to a glued on tag it seems that this receiver once served with the U.S.M.C. which probably translates to United States Marine Corps. There is a U.S.M.C. Plant Account No. listed.
