[GreenKeys] Teletype

Yes in many fixed stations were Generator powered.  all the RTTY eq was powered by portable Generators.
... the TT47 is equiped with a series governed motor.  the cycle (hz) rate did not atter as long as the 
govenor was set at 3600 rpm...  (tuneing fork or if you were lucky a strobe-o-scope) 
at 50hz though it did increase the importance of the monthly maintenance.
 
the nomen tag shown looks as if this was a machine manufactured for or sold in Switzerland.
(The "NOBsr-xxxxx" serial number  and the "xxxx:CTT" = Swiss Telegaph (Postoffice) asset number?)
