I collected all the nameplates from a Navy "CRV-52AAH Radar Transmitter" built by RCA. Part of "Model SD-a Radar Equipment". The greatly abused cabinet was at the wreckers about to be flattened (in the bin) and I was able to unscrew the tags in time. Free to a good home for the postage as usual. Jim Falls KG6FWT Eureka, CA
