[Boatanchors] POLARAD information needed

[Greg Mijal]

Hi:
Does anyone know of a place to research Polarad test equipment? I'm researching the possibility of Polarad selling Rhode & Schwarz made spectrum analyzers under the Polarad mark around 1970's - 80's.
I also have a Polarad 630B solid state analyzer and absolutely no references on the Web under Polarad or R&S. No manual and a attenuator problem to fix.
Thanks
Greg
