In terms of "what" I'd say it was vacuu-formed styrene with an enamal paint finish- the 2nd picture alone tells me it's probably no more than 1/32 of an inch thick at best- as can be noted by the visor ["ball cap"] bend to the right of the picture...
I hate to say it, but if that visor is see-through, it seems awfully matt-gold to be see-through; at best I'd say it was clear styrene with gold paint sloshed around ont eh interior of it...
Is there better photos by chance, depending on the price for it, I'd be wary of it's quality myself.
Now- as to "whom" may have produced it, I wouldn't have a clue unfortunately...
