[GreenKeys] The Iron Horse in action...

[Duncan Brown]

Here is another picture of a WU multiplexed operating table. (Mux 
Operating Table - WU).  The perforator is a "Multiplex Perforator 2A" by 
Morkrum (aka "Iron Horse"). There is a "Multiplex Transmitter 1-A" and a 
"Multiplex Printer 1-A", both by Kleinschmidt Electric Co.  The box 
behind the tape transmitter is a "Multiplex Automatic Control 1-A", also 
by KEC; it is finger-powered and generates a FIGS-J-LTRS code 
combination to ring the bell at the other end without disturbing the tape.

This came from a c1925 WU book on Multiplex Printing Telegraph Systems 
with a lot of good photographs & drawings.

There are photos of a couple of printers I had never seen before - a WE 
Mux Printer - WU 1A and an unidentified manufacturer Mux printer WU 5-A. 
(pictures enclosed)

Have you ever seen these printers?

Have fun & 73,

Duncan
