NOTE: People couldn't view the images when hotlinked from Helmet Project (Nationalchamps.net), so I copied them all over to imageshack. Let me know if you're still having issues.
Saw a piece on Pat Devlin's draft prospects (remember him? Former 4* QB who originally committed to PSU, but transferred to Delaware after 2 seasons, following the Joe Flacco model) and saw his Blue Hen winged helmet. Made me wonder which college teams are currently sporting these helmets. So, thanks to wikipedia and the Helmet Project, I've put together a summary (with images!) of all winged helmets currently used in college today, as well as some historical helmets (ie, no longer used or from defunct teams). Don't know if I've missed anything while scanning through Helmet Project, but should be as comprehensive a list back to the 1950's as you'll find.
For additional reference, you can always check out the excellent write-up on the history of Michigan's winged helmet at the UM Bentley Historical Library website. And because I know some Sparty-sympathizer will bring it up, there is also an unofficial "Official" history of the winged helmet courtesy of Spartan Jerseys (and unlike UM teaching notre dame to play football or our marching band teaching ohio state's how to spell, msu just used it before UM; UM drew no inspiration from them. If anything, Michigan "inspired" msu to STOP using it after a 50-0 beatdown.).
