generally they were just toughened glass..the type that shatters into millions of bits..

i believe laminated without a band were optional..thats the type that cracks...absinth can tell us the answer to that one..

and then of course are all the aftermarket laminated screens that had coloured bands across the top..

and today when you ask for a laminated screen for your van you generally get the wb type which is banded across the top and black around the edges...
