[Hallicrafters] MYSTERY SX-117 - WHAT IS IT?

[k7mks at comcast.net]

I have a rather unusual SX-117 and would appreciate comments on what it is.  The set has: 

  

1 A shiny aluminum chassis with NO identifying tube types, control names, or rear panel connector labels. 

    

2 Square openings thru the chassis do not have a clean appearance. There are scribe lines on the chassis in some areas.  

  

3 The 1600 and 1700 crystal sockets are not parallel to each other - it is almost like someone hand drilled th e m ounting holes. 



4 Several screw holes are somewhat elongated.  It is as if someone wanted the hole to be larger. 



5 Wiring and soldering do not have that "production" look - its a bit sloppy. 



The front panel and cabinet are pure SX-117 



I'm starting to think it is an  engineeingr or pre-production model 



I have no use for it and likely will offer it for sale. 



Comments are appreciated, thank you
