AHI-Azrak Hamway International, Line Mar Toys "Elegant Miniatures" were two names of American firms that imported tiny die cast toys from Japan in the 50s. They must've still been available in the 70s because I remember a box of four antique cars and a train set that I still have. They were more on the "cute" side then the scale model side and they were made of the toxic alloy called "antimony" in medieval times. Here are the planes that I have.
