Volley gun
The Ribauldequin was a medieval version of the volley gun. It had its barrels set up in parallel. This early version was first employed during the Hundred Years' War by the army of Edward III of England, in 1339. Later on, the late Swiss army employed it.
William G. Morgan
After creating some ground rules, William Morgan had to experiment with his game. First, he had to decide which ball to use. A basketball was too heavy while the basketball bladder was too light. After testing all of the balls he had available, he had come to the conclusion that his best option was to ask A.G. Spalding & Bros. to make him a ball. A young A.G. Spalding & Bros. equipment designer and master marine cloth tailor, Dale Callaghan, developed and produced the first prototype volleyball. Morgan was very pleased with Spalding & Bros. work. They created Morgan the perfect ball for his sport, which was covered in leather, with the circumference of 25–27 inches. The ball was also the perfect weight for Morgan's sport. The ball weighed 9–12 ounces. This new ball that had been made for Morgan's sport was the perfect finishing touch to the basics of the sport. The last thing that had to be done by Morgan was to create a name. Morgan came up with "Mintonette" as the new name for his game.
