Does anyone else's Trophy have this?

[PS CUP]

I have a square patch at the bottom of my windscreen in the centre which has a different tint to the rest of the screen! Perhaps it's been replaced before I owned it.

I would upload a pic but can't seem to do it from my iPad.

My first mk1 172 had this - I was told it was because it was an import, something to do with and area to put a toll pass (toll roads being very common in Europe) where it can be easily scanned without the window tint interfereing.
Im guessing here but I think it might have had a windscreen replacement ?

heres a photo of my windscreen spec - printed bottom right next to tax disc.

similar to ^. My very late 172 had this which was a 'break' in the metallic covering in the glass which aids radio / electromagnetic waves used for either gps devices (my tomtom was mounted there) which didnt work if placed elsewhere. I assume windscreen must have been replaced as not standard as cup spec screens which slightly thinner
