If the promo and belthanger are indeed the same, are all the spaces between grips accounted for? Especially given the orientation change of the box? Are we SURE there's no more rivets?
Using the d-ring bracket as a reference point, that does indeed seem to be the case. The two sets of rivets on the side of the flash tube are aligned with the two rivets that hold the d-ring bracket in place, which themselves line up with the spaces-between-grips that are aligned with the “A” and “L” in the “G R A F L E X” stamping on the clamp. Symmetrical and simple, since that side of the prop was clearly not the “beauty” side, and so the rivets could stay off-camera. Except for that one day of shooting in Tunisia, early on, when Hamill wore the prop on his belt backwards. Luckily for us.
