They are quite interesting cars Richard although I prefer the D2 and 3, nicer shape but these later D4's do have a nice art deco dash and steering wheel. One of the things I admire is the fact that Robert de Rovin built his own "injun" for his cars, a fourstroke twin if I remember rightly which must have been very costly to do, other manufacturers at this time were just buying in cheap two stroke motors like Ydral, Zurcher, JLO. The headlights are correct and I think the price probably is too.
