Bell Moto III & Simpson MX Vintage Helmet Comparison

I thought a side by side comparison of vintage full face MX helmets would be something different. The Bell Moto 3 was pretty much the standard for Moto Cross and Off Road riding from the late seventies on into the eighties.
The Simpson is a nice looking helmet but does not evoke images of that period like the Bell does. Who can forget Bob "Hurricane" Hannahs lightning bolt graphics on his MotoIII.
