Ferrari 312T3

Hi people,

I want to build a couple of diffirent 312t3's.
In scale 1/12 and 1/20.

But can people here help me out in some of the diffiret versions raced in '78.

Ferrari started with a car like this:



as raced in Monaco. (like the Protar 1/12 kit)

Then changed to:



as raced in Brands Hatch. (like Tamiya 1/20 kit)

And later changed to:



As raced at the end of the season, with skirts.

But I'm not sure exactle when they changed to the diffirent versions and were there other versions aswell.
Do you out there have some detailed pics, specialy of the car with skirts.
And it also shows that the car used skirts.
But how and when where these used?

Greetings and thanks, Roland

From the website www.aerogi.be I have these pics of the prototype Ferrari T3:


I quote from the site: "Here are two pictures of the first 'outings' of the Ferrari 312T3 during winter testing at Paul Ricard in early 1978. Compared to the final version of this car, there are some differences, especially there seems some kind of front air intakes, just next to the wheels."

Also on the site this pic:

Again quote: "And here is another picture of the 312T3 (unfortunately no info when and from which track this is taken. Note the semi-double rear wing."
