NOS Hella logo and 22.5 cm chrome bezel for the fog lights used on the 300SL,190SL and other models. Also used on Porsche 356, VW, Jaguar and other models.

This is 6.75 inches wide at the back. The lens opening is for a 143mm lens and it has the same 12mm rim all around.
I have 2 others the same shape but without the Hella stampings like on this one.

If you have to replace your damaged or ugly chrome, these are less money than rechroming.
