This is a museum quality reproduction of a WWI Oberser wing in sterling silver. This wing is 2 inches wide and from the construction the original was made up of thwo pieces solder together which was not uncommon in that era. This is a rather unusal wing design and the feathering looks a bit likt that used by Haltom Jewelers of Ft. Worth. But I have been unable to find this wing in any of the refrenances of wings they made. But many wings were one of a kind since they were all unofficial.
