At the origin of the adventure, Oliver Fisher Winchester has nothing of the cowboy. He is a shirtmaker when he invests his money in New Haven's Volcanic Repeating Arms Company, which specializes in firearms. He became president in 1857 becoming the largest shareholder. He demands that the new weapons be light (less than three kilograms) and be no more at once. It also relies on security with metal cartridges more reliable than those made of paper. It also introduces the detent to prevent stray bullets.The company then becomes the New Haven Arms Company, Winchester hires a gunsmith, Benjamin Tyler Henry, and asks him to refine powder blends and mercury fulminate to improve projectile propulsion. He produced striped cannons to refine the precision of the shots as early as 1860.
