[GreenKeys] US Navy acquires Postal Telegraph Co. tape relay equipment

[Nick England]

I was just startled by this paragraph in a 1958 US Navy Radioman training
manual
-----------
Most relay stations employ as major equipment, Navy-owned
tape relay equipment formerly used by the Postal Telegraph
Company, package units (four-in-one: send, receive,
automatic number, and monitor), and A. T. & T. leased equip-.
ment. The ex-Postal Telegraph equipment comprises receiving,
sending, automatic numbering, and monitoring units, and is
used on both radio and landline circuits. It operates at speeds
of 60 wpm on radio circuits and either 65 or 75 wpm on landline
circuits. Tape relay equipment is leased from A. T. & T.
to terminate heavy traffic load trunk circuits. It also consists
of receiving, sending, and automatic numbering and monitoring
units, and operates at 75 wpm. Navy-owned package units
are normally employed on light traffic load circuits, both radio
and landline. Each unit operates at 60 wpm on radio and 65
wpm on landline.

- I wonder how the USN came to own Postal Telegraph's TTY relay equipment?
Spun off to the Navy following the WU-PoTelCo merger?

PDF of the training manual section with photos of the equipment is at
