Hi Inski,
Another way to get a look at it would be to purchase a can from https://varietypaints.com.au/products/d13971-clr719-wattle-vw-acrylic-touch-up-paint-300-grams
CLR 719 Wattle was a Dulux colour code used on Australian assembled cars in Victoria (if I recall correctly). The cars assembled there included VW, Volvo, and I think also Datsun, probably others as well. The point being, that the cars assembled under this roof often shared the exact same paint codes. This should enable you to get a real proper look at it. As far as I know, the colour was used on VW's around 1972 / 1973.
Good luck with it.
