[GreenKeys] unusual Model 15 sighted...

[David Ross]

Greenkeyers -

   I recently saw a Teletype Corp. Model 15 with unusual sheet metal, 
and am wondering what it was and who it was made for.

   The sheet metal cover was larger than the usual Model 15 cover, and 
quite boxy-looking with lots of odd angles & sharp edges.
   The cover was wide enough to accommodate a different paper crank 
setup -  rather than the usual Model 15 crank on the platen spindle, 
there was a large rubber-rimmed wheel on the spindle.  The rubber-rimmed 
wheel was maybe 6" in diameter and a portion of the wheel protruded 
through a rectangular hole in the top of the sheet metal cover -  looks 
like it was intended that the operator advance the paper by pushing on 
the rubber-rimmed wheel with the palm of his hand.
   The entire sheet metal cover hinged up for access to the typing unit 
& keyboard -  the hinges were toward the rear of the cover.  I did not 
have a chance to look at how the cover could be removed, but when hinged 
up it allowed access to most of the front of the typing unit.
   The cover was finished in light gray paint.  I saw no labels or ID 
tags anywhere.  Looked to be a plainjane Model 15 typing unit & keyboard 
inside.

   So can anyone make sense of my brief description?  Any idea what this 
beast is?
