[GreenKeys] Western Union Motor Control Relay ?

[jhhaynes at earthlink.net]

I gather that when W.U. put machines in customers' offices they often
used the direction of line current in the loop for motor control.  I've
seen a number of ex-W.U. teleprinters and they have a fitting where the
motor control relay would go, but I've never seen one of the relays.
Wonder if anybody out there has seen one of the relays, or has a picture
of one, or has one.
