Just from looking and guessing, the half with the large variable is the
transmit side, either band switched by the rotary on that end or just
tapping the large toroid for matching.  The antenna output is the screw
with knurled nut.  It has a pushbutton on the side  for the key and a
crystal socket.  The back half is the receiver with a volume control and a
phone jack output, and is either multiband judging from the rotary switch
full of toroids, or that and the small variable tunes the full length of on
band.  One thing that is not obvious if it is a CW rig is a BFO circuit
that should have an inductor.  Replace the bad tube, put a crystal in it
and fire it up.  Looks like all it needs is filament, B+, and ground.
