The Austin A90 Atlantic looks to be pretty much what it is - a scaled down 1950s car decked out with the favoured styling cues of the time (whitewall tyres, streamlining, convertible or convertible-look, fabric coated roof, chrome stripes etc) - designed for the export market, particularly the United States. It also features 3 headlights, the central light for beam, a detail that can be seen in a few other cars of the period. It wasn't a particularly successful design and didn't achieve much market penetration in the U.S. We came across this example in a meet-up of car enthusiasts on the promenade at Weymouth, Dorset.
