CIA communication pre-Twitter?

Lamson Corp installed a pneumatic-tube mail-delivery system in Original Headquarters Building (OHB) during construction. System had more than 30 miles of 4‑inch-diameter steel tubing. At the time, this system was one of the world’s largest.
The original system had about 150 receiving/dispatching stations throughout OHB. Shown here is one of the many vacuum-driven carriers that sped along the system, moving mail from one station to another. The system operated from 1962 until 1989.
