Welcome to Tnet.
Nice piece of family history to have.
Bangor Punta was a huge American conglomerate, formed in 1964 and based in Greenwich, Connecticut. They bought Smiith & Wesson from the Wesson family in 1965 and diversified it into accessories such as holsters, as well as law enforcement equipment such as handcuffs and breathalysers. They also bought Piper Aircraft from the Piper family in 1969 as well as a number of other well-known companies across a diverse range of markets. The Bangor Punta Corporation was bought by Lear Siegler, Inc. in 1984.
That’s clearly a Smith & Wesson logo on the pendant, so will be between 1965-1984. Those with a Piper logo will be from between 1969-1984.
I don’t know what these pendants were for, but they look to me like the kind of thing that might be given to employees as service awards or for sales achievements.
