In 1947 R.D. Hull arrived in Tulsa with a strange contraption that would forever change the sport of fishing – the first closed-face fishing reel.

The more unusual thing about Hull’s invention was the company he would eventually partner with to manufacture his new invention – the Zero Hour Bomb Company. The reels went into production in 1949 using an acronym of the company’s name – Zebco – and before long this side business took over and the business stopped making bombs altogether.
