This is a very early instrument used by late 1930 broadcast stations. It
combines a VTVM, frequency and one other instrument, I found one that I
shipped to a gentleman a few years ago who was building a museum. If you
can't find any more info I think I have a few pages of documentation
somewhere. Supreme was based in Greenwood, MS. and is long gone. The nice
feature as I recall was the wooden cabinet.

Does anyone know what this piece of test equipment was used for? I can't
find any information on it. Thanks in advance for your help.
