[TMC] New TMC item here

[telegrapher at att.net]

Returning from a scrounging trip where i landed a TMC O-330B/FR.  RF
signal generator like a VMO or VOX i suppose.  Has the variable
frequency readout in the center on the right side and different modes
(HFO-BFO-) switch selectable inside little door kinda towards the top
left side. 
Heavy mutha as well.  ANyone know anything about this or have a manual
for it?  LIke to put it to work in the station here.
