[GreenKeys] M26 on Ebay...

[Jim Haynes]

There probably was a bulletin on the table, but would be hard to find
in view of its age.  The only book I have covers only metal tables.
I assume M26s were never made with metal tables.  Then there should also
be some Bell System Practices about Model 26 stations.  The subset would
probably not have been put into the table at Teletype, but in the field
at a Western Electric distribution center or at the Bell operating
company where it was to be used.

TWX stations prior to Dial TWX used a variety of stuff in the field.
Some were operated over 20ma wire line loops.  Others used a single
channel of 43A1 carrier to operate over a voice-grade line.  Some were
arranged for unattended answering, hence a motor control arrangement.
Many were arranged for attended-only service, the concept being a two-way
conversation by teletypewriter.

I'm going to try to attach an Illinois Bell set of drawings for Model 15
stations that would be similar to the way Model 26 stations were wired.
