[GreenKeys] another Model 19 saved

[dmm at lemur.com]

Since we're talking about successful machinery hauling, here's
another.  I just got home with it today:

http://www.lemur.com/temp/model-19-set/index.html

It's a Model 19 set, pretty much complete.  It may look a bit familiar
as it was on ebay recently.  It didn't sell there, but later the
owner was willing to part with it for less.  Under the dust, it seems
to be in pretty good shape, really.  I'm particularly glad that
it has the relay and the table/rectifier (and of course the punch -
this is my first 5-level punch).  I've still got a lot to figure out
about it, and some basic cleaning/hookup/testing to do.  (The Model 5
Linotype is firmly at the head of the project queue right now, though,
so it may be a while before I get to this.)

Two questions:

(1) The unit is painted a sort of gray-green, which to my un-military eye 
makes it look military (but it isn't an olive drab sort of green).  
The badge on the front, though, says Bell System Teletypewriter Service.  
There are no obvious military markings on it.
Is it likely that this was a military or a civilian unit?

(2) What is the name/designation for this set overall, inclusive
of the Typing Unit, TD, table, Rectifier, etc.?  Is it correct to
call it simply a "Model 19," or would it be a "Model 19 Set"?
Or would it be something else?  The Teletype Corporation's otherwise
laudable habit of making everything modular does make the question
of naming collections of modules more difficult.
