Whatisit? PreWar Christmas Quiz day 2

For part two of our six day quiz we found a rear end that looks more like a poached egg, than a car. But that's only from behind! The front has a very distinguishable shape, much resembling a horse shoe. This one is red, but many of the make, especially the racing types were blue.
Write down the make, but please DO NOT send us your answer before the last quiz has been published. Of course you can contact us on all other topics, because the PreWarCar offices are always staffed! From the participants with all answers correct, six names will be drawn at random. All six winners will receive the famous PreWarCar T-shirt. Good luck and if you like puzzles, try your hand at the PostWarClassic Xmas Puzzle. Enjoy this holiday season!
