If there is a brand that can be considered the mother of the hobby of collecting die-cast airplane models, Herpa would be it. Historically a 1:500 scale brand, today Herpa is also very active in the 1:200 scale world. They also occasionally produce airplane models in other scales, including 1:400. Herpa's catalog, especially in 1:500 scale, is impressive. They also enjoy worldwide recognition beyond the airplane model collecting community.
