The ball is classed as a torpedo shape, basically pointed at both ends. The American football was based on the original design . The size, weight and air pressure used to inflate the ball are governed by the NRL and IRB regulations. The are now a number of manufacturers of Rugby balls the oldest being Gilbert of UK who produced the first balls used in the Rugby School Warwickshire England. They were made of leather outers with pigs bladder inside which was inflated to make the ball. They are now made of a synthetic polymer with a silicone inflatable bladder inside
