Its been nagging at me ever since I posted the alert to the ad on Subito

I knew I had seen something similar to this colour on a S1 Ti before, but where?
It is not a colour that I can find on my old colour charts from the period the S1 Ti was in production: late 1973 until late 1977.
It turns out there almost certainly was a similar factory colour, but only for a very short period of time, possibly in late 1976.
It goes by the name of Verde Pino and seems to be a solid colour, where as the Ti on Subito looks to be metallic, so although a dark pine green is almost certainly non original.
Sadly I have not yet found a colour code for Verde Pino.
Here is a pic of a French registered S1 Ti in this very unusual Sud colour.
Maybe this is the rarest Sud factory issued colour of them all
