Had VERY little time tonight but I took his face off and was able to manually move the eyelids left / right by hand.
All the 'couplings' are intact ( there is like a steel hook from either side that hooks into a central nylon plate, all that is rock solid )
There appears to be a couple of VERY small coils in his head - will see them better when I get it all off /out.
One coil for each direction?
Tell me this aint gunna be electrical please - they still 'shake' they just dont move all the way left or right in gameplay - but do so EASILY manually.
