[comp.dcom.telecom] Identify This Instrument

Donald Ekman <ekman%wdl30@wdl1.wdl.loral.com> (05/07/91)

Somewhere along the line I've acquired an old telephone instrument,
which I can't identify as to where it might have been made and used.
Perhaps someone can help me.

It's an Elliot Ness style, upright phone, with separate transmitter
and receiver, the latter being suspended from a fork on the side.
There is no dial, but the instrument obviously was intended that one
might be fitted, at least as an option, so presumably it does not
predate the Strowger switch.

Inside the (rather heavy) base plate is a simple wiring diagram, and
various bits of notation, the most prominent of which says:

   TELE No. 150  (MARK Z34)
   When the DialAuto No. 10 is not fitted,
   terminals T & TD must be strapped.
   
In the wiring diagram, the transmitter is identified as Trans No. 1,
while the receiver is identified as Recr Bell No. 1A.

Anybody know where this thing comes from?  And when?

Thanks,
