I knew I would have to explain. I know better. but when I received this helmet it was very dirty and the liner was extreamely dry and brittle, along with the chin strap. so I did the dumbest thing ever by trying a little Obenauf brand oil on a small part of the liner and ultemtely did all of it. Helmet #S hkp64 4138
liner strap and shell are origional. dome stamp also visible.
