[GreenKeys] Odd Typing reperf on Greenkeys

[Don Robert House]

Nothing really odd about an FRXD.  They are somewhat rare however.

The FRXD...
A machine for sending messages cross-office. Based on the Model 14 
Typing Reperforator and a special transmitter-distributor with a 
climbing head, this RT unit would take traffic from one circuit and 
resend it on another circuit. The climbing head enabled the device to 
read the last character punched by the reperforator.
