Vintage 1970's-1980's Rawlings Kansas City Chiefs football helmet

I have listed a Vintage Football helmet, Kansas City Chiefs size Medium. it says rawlings on the back, and has the standards stamp in it which I believe has the date code on it of 9-80. So September of 1980? Just a guess.
Helmet itself is in good shape, no breaks or cracks, just scuffed up. May polish up nicely. The decals are good, but one side looks to have been removed at one time, and replaced about an inch above that, leaving residue where it once was.
Inside is a little dirty but all there.
chinstrap is missing
facemask has a crack on the wearers right side where the rivet has pinched it.
Sold as is!
! Any questions please ask.
thank you
