[GreenKeys] I know the dataphone but from teletype ad what is this terminal device.

It's a Dataspeed Type 5 transmitter - one of my projects at Teletype.
>From the photo it looks like the woman has only one leg.  And it doesn't
show the cables running from the equipment to a wall box where part of
the set was contained.  And that doesn't look like the correct Dataphone
for a Type 5 sender; it was smaller, as I recall.

Type 5 was a 75 char/sec system which took advantage of the 402 type
Dataphone data sets.  The transmitting set was quite cheap and compact
and used a circuit similar to that of a Touch Tone dial.  So it 
transmitted 9 tones in parallel.  The rest of the sender was in a wall
box like those used in key telephone systems.  It contained reed relays
to store the characters from the tape reader and their contacts controlled
the oscillator frequencies in the data set.

An alternative version of the Type 5 sender was in a tall cabinet like
Dataspeed type 2.  It had tape reels and such.

The receiver was rather expensive, both the data set to receive the
parallel tones and the tape punch.  The receiving data set was not
contained in the telephone, but was in a big box like the synchronous
data sets, with a little telephone attached by cord.  The receiver used
the DRPE tape punch, the first product using that punch.
