I agree they are def the same base helmet, all pulled from the same mold im sure. What i am seeing is the entire cheek panel slightly....ever so slightly.... twisted. Which i think did in fact force some flare to the helmet. But that said, i think its less than i originally perceived.
I tend to agree with its all in the angles, but no matter how i hold the MR it never looks like what i see in ESB unless i pull the sides out a bit. So i dunno . We could probably go on about this until we are old n gray..but i dont think we'll ever truly know why we see that flare in ESB.
The measurement of the PP2 according to Keegans post above, is just under 9.5" wide. Mine is 10" so when i do V2 i will take it down a notch and see what i get. Or i may just do a new scratch build. Not sure yet. But all of that said, this will just end up my interpretation of the ESB helmet and whether or not it is truly "right" would likely be irrelevant because there is no way id be able to get all aspects of the helmet dead on, or even that close. Without linage its just a fan sculpt, and for my helmets, im fine with that. Im not going to tout it as the best helmet ever lol.
