This is a museum quality reproduction in Sterling Silver of an original wing. The wing is hallmarked LeBreve of Paris and is 925, the European designation for sterling. The wing is 3 1/8 inches in width with the “US” letters 24-karat gold plate. If you view this wing closely it is an almost exact copy of the Hummrichous wing from Memphis TN. That wing was made in three parts and this one is soldered together.
