One of the last and, in my opinion, best die cast ranges for toy airplanes {as opposed to collectible ones by the current Corgi, Armour, et al} is the Aero Mini range. I met the founder of the firm who told me that he started the toy line because as a former Naval Aviator { flew F-4s which explains why there were some in the Aero Mini range} he couldn't find realistic, well made scale model toys for his children. On a trip to europe he found a Tekno DC-7C and thought it was the best one around, and that one sparked the concept of the Aero Mini line.
Any way I doubt there is any airplane collection today that doesn't have at least one example of an Aero Mini. The firm ceased operations in the early part of the 1970s making all of them around 40 years old.
Here is an unusual one:
They are many toys in the range as this early 1960s ad in a magazine shows, but there are many others not listed. I wonder how many chromed American Airlines 747s are out there? I have been looking for 20 years and haven't found one yet.
