The 1967 National R-1490/GRR-17 HF receiver is reported to be the last military receiver ever designed and manufactured by National Radio Company.
Along with the AN/FRR-24 and the R-1230/FLR, it represents the very best of National Company's engineering talent.

This example is missing one of the modules, cables, and a few other minor parts. If you have any spare modules or parts, please email me.
I would like to restore this receiver to operating condition.
