There's so many grey areas - I knew two different people in the 1990s who had stormtrooper helmets (done completely separately) that were made with molds taken from a screen-used ROTJ helmet (I know one was screen used because I held onto a $20k helmet for my buddy for a week and matched it myself), which was not exactly rare in that era.
So "fan-made," but taken from an original (yes distorted ROTJ) helmet.
Then there's a manufacturer like Shepperton - hard to say what exactly that is, being the original contracted manufacturer of the screen used helmets (yes I get the debates) but sued by LFL, yet winning. "Licensed" in 1976, "unlicensed" decades later.
That RS is gorgeous. Funny that Hasbro seems to be inching closer and closer to the high-end helmet market with each BS release. Would never have believed that. You have to wonder how good a Hasbro ATAT helmet will be when they get to it, hopefully ditching those silly exterior battery compartments and minimizing the mold seams.
