Interesting.  I see something else.  Everyone sees things differently I
guess.  On the transmitter (top unit) I see two little arced windows for
tuning indicators and they are co-located with the (albeit small) tuning
knobs that are below. Those windows - if you look carefully - clearly have
little band or scale labels down each side indicating there are multiple
scales (maybe bands).

The lower half receiver has one of those windows at the top and similar
(maybe) tuning knob at about the same level down as the transmitters.   Both
units seem to have switches that could be band switches.

I think they are tunable.  The two units clearly are a pair and it looks
like (unlike the front panels) that there is just one big master case and
the must be internal wiring between the two because there is a bundle of
wires going in the lower unit and none to the top one.

Maybe I am imagining things but I think I see a key jack on the right hand
side of the lower panel above the other jack.  I can see the "Y" in the
label that has just three letters.  I do not know another likely label that
has only three letters.

So the lower unit (maybe) is receiver and transmitter control and the upper
unit the transmitter (maybe amp).

Curious beast.

Went right to the pic and started to do some research, including your site
before I realized it was you doing the asking.  My first thoughts were
perhaps it is airborne gear due to the power connector on the front panel,
there is no tuning knob, suggesting channelized operation, it appears to be
a RX and TX in one box, it is mounted on shock mounts, but then again, so
are the TCS series.  The radioman is wearing headphones which look like they
are plugged in the front of the lower unit, but I see no jack for a key on
the upper.  The odd thing to me is the speaker on the front panel, nothing I
have except morale radios have a front speaker and have never seen an
airborne set with a integral speaker. Noticed on your site and Henry Rodgers
site a few with what looks like a front speaker though.   Wondering if it is
a set on the channelized HF marine band freqs, and for that matter, when
were the marine freqs laid out channel style back then?
