[Hallicrafters] What is it?

[TVComlGuy at aol.com]

Hi to the group,
 
I have a mystery radio that I am trying to identify.  It looks to be a  
military receiver built with a heavily modified Hallicrafters front panel and  
cabinet from the S-85 through SX-100 era.  It is general coverage from 1-52  mc.  
It uses 16 tubes.  The front panel has 4 test points marked  TP-1,2,3,and 4.  
The back has 4 BNC connectors.  There doesn't appear  to have anything marked 
audio output or phones.  It looks to be well  constructed and may be either 
home brew or a prototype.  I can send  pictures to anyone who might be able to 
help identify it.
 
Thanks,
