Christies Late Roman helmet: 1 or 2?

[markusaurelius]

The nasal area and other parts look very much restored. The iron area is smooth when compared to the other parts of the corroded iron. The same goes for large parts of the cheek pieces. Me thinks it may be based on some fragments, and has been heavily restored in the image of the Christies helmet.

Or it is a fake, based on the same flawed original fake. Two helmets being so identical I find hard to believe, even down to the hinge shape, cheek piece hole, number of rivets etc.
