I only have the one pic for the underside. The rear cowl vents have a fine mesh screen. No markings, the line going across the center is just dirt but there are 2 vertical brace lines on the underside which are hard to see, about half an inch wide or so. I didn't see any logos anywhere and I am unsure of how old the hood is, it could be 25-30 years old for all I know.
