 
October 5th 1940
We know... we 
know,  this is not like finding the Holly Grail or even Geraldo Rivera 
opening Al Capone's Vault, but you might agree it lay somewhere in between for 
us helmet geeks?   There has always been speculation on when the first 
Tenite "plastic" helmet made the playing field.  Many thought it was after 
WWII when John Riddell released his new patented helmet invention to the military.
