High school prototypes are not that common. If there is one, like most teams, that means that they are probably
going to change their team's helmet. I only know of a few. If you know of any, please contact me, via e-mail, at: firstname.lastname@example.org
Vienna Mathews Mustangs
Mathews decided to change their helmet in 2006. I know a graduate of Mathews and he knows a lot about their helmet history.
Here are a few prototypes of Mathews 2006.
