For my money a fake.
A closer look at the spring clips and internal spring set up would help but I tend to agree with Doug
Not a good sign that it is mounted on a faked helmet
In case had been real probably the guy would have found a original ND helmet at around 3-400 bucks to put his expensive SS cover on top instead of that fake wire helmet...
Thank you very much for your help guys! very helpfull like always!!
