Yep, Diahatsu it was, ours was also V reg but there are no photos of it, that was the only picture I could find on google of a brown one. The vent under the windscreen was just a spring loaded flap, handy as ours had a previous life with a game keeper and smelled horrible all it’s rusty days, we never tried folding down the windscreen, I’m not certain you actually could.
