The creased rim looks good but it appears to have paint in the pitting on the exterior?
Whatever its just an opinion.
Can't tell from those pics. Need good clear close ups of the inside rim, the maker mark, the batch number, the front of the helmet showing the curve of the visor, and the rear of the helmet showing the angle of the skirt. From these pictures I can't even tell if the shell is original. Pretty sure the paint and decal are not.
