Included the Horton-Keitch Braking Charm
The Comet 140 is a broomstick produced by the Comet Trading Company, and was released in 1929. It was designated the Comet 140 because it was the 140th model they had tested before its release. It was the first broom to incorporate the Horton-Keitch Braking Charm, which would mean Quidditch players would be less likely to stray offside or overshoot the goals. It quickly became the broom of choice for many British and Irish Quidditch teams.
