The Hercules 410 GA tear gas fountain pen projector is a unique device developed during the Cold War era, primarily used by military and law enforcement for self-defense. This pen doubles as a functioning fountain pen and a tear gas projector, allowing users to discreetly carry a means of defense. Its historical significance lies in its representation of the innovative, albeit controversial, approaches to personal safety at the time. Collectors value it for its rarity, dual functionality, and the intriguing blend of everyday utility with self-defense technology.
This projector is worth about $150.00. A replacement lamp is almost $500.00, so it won't be worth it to relamp this model.
