[Milsurplus] SCR-288 or TBX??

[David Stinson]

Troops on Guadalcanal.  
Photo item 6634752341.
The radio is sitting on a stump.
My monitor is poor (and my eyesight is not much better), 
but there are some details that point to SCR-288:

Case is square-sided and the dimensional ratio is correct for SCR-288,
incorrect for TBX.
Headphones are the type RCA supplied with SCR-288.
Antenna pole configuration as recommended in SCR-288 manual.
Generator is secured to a tree as with TBX, but cable comes out 
perpendicular to the cranks like the SCR-288 genny.

Your thoughts?
