Cerbera windscreen question (again probably)

[flyingdutchie]

I have an early Cerb (feb 1997) and t5his one should have the 50mm band. But I measure 30mm for the top and bottom band. The sides are wider. I saw that this was not the first wind screen when I got it out. So, they probably fitted the later one.

When I look at racing green website, they speak about a 30mm wide band on the top and the sides. This cannot be right? Can wsomeone confirm that is is 30mm at the top and bottom or 50mm at the top and bottom?
