[Boatanchors] Need help on McMurdo Silver RF Generator

[Tom NØJMY - AAR7FV]

My apologies if this is to far off-topic.  I figure this piece was used on
many a boatanchor in its day.

What this is is a McMurdo-Silver model Silver 906 RF generator, and it
followed me home from a local consignment shop.  It caught my eye partly due
to the meter, (which looks to be a vane-type, though not certain) which is
calibrated in uV -- and also the long test lead which ends in a group of
three old fashioned screw type binding posts.

Can anyone give me any info or insight on this rig.  A manual or even
schematic would be wonderful, too.

Tnx es vy 73,
Tom
