Sorry Tommy, I disagree with quite a bit of that!
1. This is Kyalami in 1979 - the "Dallah Avco" with Arabic script livery below the mirrors matches that used on the FW07 later in the year. In 1978 the decal in the same position simply read "Saudia". (It turns out that my own archive is a little mixed up.

)
2. This is the new Woodcote chicane at Silverstone in 1987.
3. I believe that this is indeed Estoril.
4. Very difficult - this one is unclassified in my archive.

The circuit seems to me to resemble Detroit (but the car ran with a front wing there - but perhaps not all of the time?), or Kyalami (but Jarier had a Candy sticker on his visor there, and the car had no Agip sponsorship plus no Denim "wheel" in front of the cockpit), or Las Vegas (for which I have no comparison). I have it listed as an FA1C, which would rule out Dijon (where the FA1D was used), but this may not be accurate (and I can't tell the difference between the FA1C and FA1D anyway

) I can't find another photo where the car's air vents are covered up (as they are here).
Here's a list of problems, based on the car's appearance only and not what the circuit looks like:
South Africa - Candy visor strip, no Agip stickers, bolt on nose below number instead of between the 3 and the 1.
Brazil - Candy visor strip, no Agip stickers.
Long Beach - no Agip stickers (only Paletti for reference).
San Marino - no Agip stickers (only Paletti for reference).
Belgium - front wing used.
Monaco - no photos to compare to.
Detroit - front wing used.
Canada - front wing used.
Netherlands - sponsors match up, but the "31" spacing is slightly different.
Great Britain - sponsors match up, but the "31" spacing is slightly different.
France - no photos to compare to.
Germany - no photos to compare to.
Austria - no photos to compare to.
Switzerland - Candy visor strip.
Italy - matches.
Las Vegas - no photos to compare to.
My hunch is Las Vegas, but I can't prove it!
