I know it's a rookie question, but it's ok, I'm a rookie at this. I've been trying to figure this out from pictures on different dealer sites but I can't. What is the difference between an M35 and an M40 helmet? And am I correct that the difference on the M42 is the flare or lip on the bottom edge of the helmet?
Also, out of all the books on headgear and/or helmets that are listed on this site, which one would you guys recommend as the best to educate the beginner?
Thanks
John
