Bjørn - my best guess for the white one would be Rolf Stommelen's 904-102. Originally delivered in metallic silver and raced like that during '64 and '65, he resprayed it to white for the '66 season. However, there are big "dark" stripes on and below the front bonnet on all b&w photos I have from that year. I cannot recall having seen it live that year, so that I cannot substantiate what colour these were.Originally posted by Bjørn Kjer
...but the last 3 is a bit mysterious to me [...]: 1 plain white , 1 medium blue with yellow strip and 1 light blue ! Perharp someone can put some light on to what was going on in my head 40 years ago ???
Medium blue with yellow stripe ? Guess it may look great but it does not ring a bell with me.
Light blue ? There were two cars delivered in "enamel blue", 904-032 to Rudolf Moser (who, unfortunately had a fatal accident during practice of the 1000km Nürburgring race in 1964) and 904-075 to Jacques Rey. That's the one we have seen on the earlier picture posted by "jarama".
