[Premium-Rx] Cubic Transceiver

[Paul and Julie Nell]

Seeking any assistance with a Cubic Transceiver. There is no model number anywhere that I can locate on the transceiver. The transceiver is military green in color, use decade type frequency selection (6 digits via pushbutton), approximately 4 inches high by 12 inches wide by 12 inches deep, looks like it would cover approximately 1.6 to 30.0 Mhz. I realize this is not a premium receiver, but searching the internet has yielded nothing. Specifically looking for schematic/manual, or any leads to obtain such. 

Thank you,
