The wire isn't.

Helmet shell and the liner look original at least in these photos.

As for the wire - well it looks like someone has been rubbing for a decal or doing something odd on the left side so that raises questions....

Wires are very hard to date and this one is no exception. While there is some interaction between the wire and shell it’s hard to tell when it was added.

You need to have the wire in hand and check for the age where it is stuck between the liner band.
I much doubt this one is authentic. Tired , worn shells are often upgraded with wire...
