One for the modellers really - I have managed to source the original windscreen for the panhard. I believe it was also used on the earlier panhards as well (EBR).
It incorporates an electronic windscreen motor that takes its feed from the dash board. Only issue is - there's no way to turn it off or on. Its either plugged in or not!.
Visibility is actually very good and it does stop the wind (and some rain)
It is a close fit, but the canvas roof lets the side down as its not attached to the hull at the back under the gun mantle, and the rain pours in from here down your neck. The whole thing looks 'Heath Robinson' although I expect it cost a fortune to develop and make!
