I went up to Funspot that has a Hercules on location & snapped a bunch of pics with a tape-measure
I dunno how exact the dimentions I have are as I was hooking the tape from the plastic trim on top
Also the side panels are tapered the top being deeper than the bottom and also the front of the side panel being taller than the back
I couldn't get inside the head to measure from there as it was in a public place and ""had to"" play a few games with some of the other guests of the location.
box for backglass
H=37" (in back I didn't figure the full front where glass is )
W=39-3/4"
D=11-1/2" (*where the backglass is)
Top= 14-1/2" hangs over face by 3"
Side panels looked to be 3/4" thick outside to outside the head measured 41-1/8"
top = 14-11/16"
bottom= 11-3/4"
front = 39-1/8"
back = 38-1/8"
There were some ventilation slots in the back as well as a hole for the power cord.
