This used to be essential for outback travel in the days before laminated windscreens. It is a rolled up temporary windscreen for a VW type 2 Bay windscreen Kombi. This came with a 1700cc yes 1700 1973 Kombi that I bought(& sold) in 1977 in London to do the classic Aussie round Britain and Europe trip. Its basically high grade plastic that is braced with rods in a way that allows it to work as a temporary windscreen until it can be replaced. It says it still allows use of washers and wipers. Even today there are many places that you would have quite a wait for a VW windscreen replacement. As it rolls up compactly I brought it back to Australia with me in case of need but fortunately although it has since travelled to the 4 extreme compass points of Australia in T2, T3 Syncro and T5 4motion campers, I've never ever needed to break the seal on its container. It is only made for a T2 Bay window vehicle although it may fit others. Irreplaceable interesting VW nostalgia with possible practical value? The world's most travelled temporary windscreen? As an old bloke reflecting the pleasure I've had with Kombis and Kombi owners over many years I'm also susceptible to "encouraging the vibe" by giving it to someone with a good story on why I should give it to them for free.
