This is a museum reproduction of an extremely rare WWI collar insigna. Talk about ultra rare, this is it. You can’t even find pictures of this one in most of the books. They just don’t exist in most collections. Sold here in a set of two, this reproduction is of a set made by BB&B. The only pictures seem to be ads from WWI selling the wings. Most wings were jeweler designed and not official. The pursuit pilot wing is the rarest of all WWI wings. This collar reproduction is made in sterling silver and 24karat gold plated.
