150mm headlight rim that should fit all Aprilia headlight bodies of appropriate size. Stock on Ducati Monza and Mach1/Mark3, I believe.
Condition is VERY good, no dents. A nice patina with original 40-year-old Italian chrome, so in my opinion it's better than perfect. It's genuine new old stock.
If you need something crazy bright and shiny for a machine that will never be used, please go to Italy and buy one of the reproductions for much less money.
