Who drove the Jeep called "Nellybelle" on the American television show, "The Roy Rogers Show"?

Nellybelle was a 1946 Willys CJ-2A Jeep with distinctive, custom bodywork. Though owned by Roy Rogers himself, Nellybelle was driven on the show by his comic sidekick, Pat Brady (1914–1972). Military jeeps became popular in the United States after the end of World War II.

Brady met Rogers in California in 1935 while performing as a bass guitarist. At the time, Rogers—then known as Leonard Slye—was a member of the popular country-western group "The Sons of the Pioneers". The two struck up a friendship, and when Slye rose to stardom as Roy Rogers, he recommended Brady as his own replacement in the group.

Brady became a regular on "The Roy Rogers Show" radio program, and when the show transitioned to television, he continued in the role, playing himself from 1951 through 1957. While most of the show's cast rode horses, Brady initially rode a mule. Eventually, Rogers decided to have him drive the now-legendary Jeep, "Nellybelle". The vehicle’s notoriously unreliable brakes inspired one of the show's most beloved catchphrases: whenever trying to stop, Brady would shout, “Whoa, Nellybelle!” or “Whoa, Nelly!”

Years later, the iconic Jeep found a new home when it was sold by Christie’s for $116,500.
