WW II 3 inch Observer Wings. These are a very well made museum quality reproduction of the Luxenberg design in Sterling Silver of' an Observer wing in the 3 inch size. Wings sold by Morrie Luxenberg are one of the most sort after wings from WWII. These wings were sold only in one location in New York City. This is a 3 inch wing with pin back which is very hard to find and from a not so common maker thus missing from many collections.
