Girandoni Air Gun (original 1780 example)
The 1780 Girandoni air rifle was a 22-shot, magazine-fed pneumatic weapon used by the Austrian Army. Its buttstock served as the air reservoir, requiring approximately 1,500 pump strokes to reach an estimated 800-850 PSI. While innovative, its complexity led to its eventual abandonment, though it predates firearms like those used by Lewis & Clark.
