Christies Late Roman helmet: 1 or 2?

[Diocle]

If this helmet has been sold, there should be some expertise made by some historian, archeologist or expert in ancient weapons ... nobody would pay for an ancient artifact without some expertise ... it would be madness,

So, do you know who made the expertise about this helmet? Is it possible reading the expertise about this hemet? or even finding it?
It would be absolutely interesting reading the motivations backing the autenticity of the artifact, at least it may be a good starting point for our thoughts ...

Anyway fake or not, I'm in love with this helmet, if it's a fake , well ... anyway it's wonderful helmet! (and an absolutely high quality fake, made by an exceptional craftsman!)
