Just going back through this thread and have a B and W photo of the Orchid Special, believe the car is now in Europe [ Switzerland ] with a Michael R Rohrmoser. Have seen a recent photo of the car on Facebook.
This was in the paddock area at Pukekohe in April or May 1966.. along with a Buckler or two and other Sports Cars.
Cannot help with the colour, except must have been a dark colour !!

Please ignore the spelling and details on the photo, as when edited I didn't even know about the " Orchid Special ", thought it was a Buckler - the De Joux style body used.
