Alexander Lion Helmet- Real?

[Giannis K. Hoplite]

They coppied Connolly,but made it all bronze,while he interpreted it as iron with bronze hair.The Sidon sarcophagus,however,was all yellow,implying either bronze or skin color.Personally i believe it is supposed to represent a helmet and not the actual sking.Two main reasons.It has a neck guard separate from the cheek piece and It is too small to be an actual lion skin.Has anybody seen a real lion skin on a man's head?It is huge.Also,the lion skin usually shown on coins on Alex's head also has the rest of the skin on his showlders.The same is with the fresco over Philip's tomb.This is only a head protection.I'm not saying Alexander ever wore such a helmet,but in this sculpture he is supposed to be wearing a metal helmet.
I have a photo of similar iron helmet,but it is medieval.
