[Hallicrafters] HELP WITH CABINET IDENTITY

[W4AWM at aol.com]

Greetings fellow Hallicrafters lovers,

I picked up a cabinet today which has a label on top stating: 

Signal Corps     U. S. Army
Case, Receiver 
CY-1260G
The Hallicrafters Company

It accepts a 19 inch panel and the overall dimensions are 20 1/4W X 13 1/8H X
13 1/2D. There are a couple of chassis slides at the bottom and the unit has 
small shock mounts. It is painted in what I would call St. James gray wrinkle 
finish, but since it says Hallicrafters on it, I kinds doubt it was for a 
collins receiver.

Does anyone have any idea what this case was used to house? Is it possible 
that it was for the R-274 series receivers?  I have never seen a photo of one of 
these receivers in a separate cabinet, only rack mounted.

73,

John,  W4AWM
