Thanks Graham. Now i've looked closely at the photo, it does have "La Carrera Panamericana" written just above the door. 

But I suspect it is the same car. It's certainly from the same part of the world, and the same sponsor, Trinidad Y Hno, a Cuban cigar and cigarette brand, so it would be surprising if they hadn't taken part in the Cuban GP.

I'm almost sure I've seen a photo of the same car racing round the streets of Havana, maybe a different number. I may still be tempted.
