This vintage Amphenol Signal Commander Model No. 840-13, $75, is working as best I can tell. It does not have a manual. I have printed out the frequency bands per the channel selector, which appears to be for the original VHF television channels.
Contact me for pickup or shipping options; pickup is in Northridge.
