You can see this clearly if you compare the eFX with the other helmets from that Rick Baker mold.
The assumption here is that sithlord's helmet from the Rick Baker mold is the standard by which any future casting should be judged. This is being maintained because some have wrapped their entire reputation and the value of their being around this casting.
....the dome is clearly not from the Baker mold but from another source (not from an authentic cast i think)
This is simply untrue.
Only the facemask is casted from the Baker mold but certainly not the dome.
Again, simply untrue, but it is interesting to see that you are willing to state this as fact when you have nothing but comparison pictures from someone who is notorious for horrible comparison pictures. Also interesting to see that you are willing to publicly call eFX a liar.
