Just a thought on this; I don't believe that's actual metal, but thin Plexiglas or acrylic, perhaps with mirrored window film or silvered pvc vinyl on top.
2 reasons why I say that:
1. Weight. Even thin metal adds weight quickly, especially to a facial appliance.
2. Safety. All it would take is one bump into another person, and two people will be going to the hospital.
Thin acrylic and window film can both be purchased at any decent hardware store.
As an afterthought: can you contact whomever posted that picture online, and see if they know anything about that appliance? If they know the wearer, perhaps they might be able to find out for you what was used.
