OK, I suppose I've spun this out long enough now ...
The car is actually 'Green' - but it's not that straightforward.
It's officially 'Verde' 95-37977 - a colour that wasn't offered as standard on Spider models in Europe, but was in the USA where it was referred to as 'Apple Green'.
This is what it looks like (the seller's photos):
Although I've collected the car I haven't had the opportunity to take any pictures yet.
As mentioned earlier, the car still has its original paint code sticker on the underside of the bootlid so I'm just waiting for confirmation from the Factory as to whether it was a special order colour or some other explanation.
This car was manufactured close to the end of the boat-tail production & RHD models represented such a small portion of the overall numbers that it's well known for them to differ in many ways from equivalent LHD versions.
In case anyone's thinking
"aah, it's obviously a LHD USA model that was imported, converted to RHD & had the Spica injection system replaced by Webers"
- LHD (USA), LHD (Euro) & RHD models all had their own unique model designation number & chassis number sequences ... so that rules out that possibility
For those interested in statistics, here are some production details:
Total number of 1968/'69 1750 Spider Veloce models manufactured = 5602
This can be broken down as follows:
LHD Euro models - 2786
LHD USA models - 2215
RHD models - 601
Obviously the RHD models were destined for South Africa, Australia, Japan, etc in addition to the UK & it is thought that 223 of these RHD models came to the UK.
Currently there are details of 133 RHD '68/'69 1750 Spiders listed on the Duetto register with the following colour spread:
Red - 92
White - 16
Blue - 7
Ivory - 5
Green - 1*
Black - 1
Plus:
Yellow (non-original) - 1
Bare metal (undecided eventual colour) - 10
The one green car listed is in 'Verde Inglese' (BRG) which
was a std colour.
So it looks as if my car may well prove to be unique in respect of being RHD & this particular colour.
