Vietnam Helicopter Tail Rotor Chain Bracelet From A HALTRON 3 / Seawolf Veteran. From end to end is seven and a half inches. Has markings on each end ( see photos for details). This came from a Seawolf veteran but unfortunately the name has been lost over time. But it was bought off of Ebay years ago when B Rutledge was selling of HALTRON three items to raise money for their college foundation the SEAWOLVES were sponsoring. Has been worn but still in great shape. Super tough to get.
