It was believed in WWII a series of wings were sold just across the border from many of the Texas training airfieldsand that they were made in Juarez, Mexico. These wings are very distinctive by the upsweep of the wing tips. But this is not true. The wings were made in New Jersey by Walter Limpe. But to this day they are call Juarez wings. This is a museum quality reproduction of the Observer wing in sterling silver andn is 3 3/16 inch wide with the proper pin back.
