Thanks for suggestions guys. I do have those Shell year books among others showing these decals on various cars, but none are good enough to use as a reference. Your photo is the best I have seen Ken, and as luck would have it, the very car I am modelling, the 49T as raced at Puke and Levin 1968 ( I was there) before the big change to Gold Leaf colours at Wigram. Will scale it off as best I can and consult a graphics dude. Good work team!!
