When my Dad played for the Hartington Wildcats in the mid-40's, only the seniors got to wear the hard helmets. Underclassmen had to wear the leather ones. He's sitting in the next room (at the age of 95) devouring a book, so not everyone who wore leather helmets got CTE. The game was just different then.
Shitty pic, but here's the upperclassmen ready to head into battle. Dad is #41, FWIW.
