SWEET HELMET!   2000s Riddell VSR4, size large, Metallic White.  Cardinals and Jets.   Has the very rare “Denver Front” hole on the front of this helmet, but is missing the very inflatable bladder under the front bumper pad.  Still a very rare helmet with less than 5% of the VSR4 helmets had this feature and they were used in the NFL.  That’s why you don’t own one and have never seen one.  If you have the bladder, this is a helmet for you.

Great condition, great paint, very light wear, complete with all padding except jaw pads.   Perfect for your project.  Pictures show the great condition of the helmet.
