Cancelled 100-share certificate. Robert Gardners' company provided the first effective speed controls for steam engines in 1859. The Gardner Governor Company manufactured his flyball governors, which in time led to the production of steam pumps and high speed vertical air compressors. By the turn of the century, this steam pump technology was adapted for use in mud pumps, which became part of the oil and natural gas well drilling process. In 1927, the Gardner Governor Company merged with the Denver Rock Drill Company and became Gardner-Denver. Gardner-Denver was acquired by Cooper Industries in 1979. Today, Gardner-Denver provides compressed air and gas, vacuum and fluid transfer technologies to industries throughout the world. Condition: Crisp and excellent, no fold lines. Certificate measures 8 x 12 . Shipping: $1.83 via 1st class.
