I'm afraid I can't really answer your question. But I really do think it's important to get passed this idea of "buying scale accessories" as soon as possible. You don't "buy" scale accessories, you "build" them! While extremely commonly produced models like the Mustang, Corsair and Spitfire in common scales have created their own miniature scale accessories industries, always looking to buy what you need is, in the long run, an extremely limiting approach.

Items like antannae, guns, and radiators are relatively simple to produce. And ultimately a lot more satisfying that gluing some store-bought bit to the surface of your model.
