Brains bust designed by William K. Harper and produced by Beswick of Longton, England, in a 1992 limited edition of 2,500. Brains is a fictional character introduced in the British mid-1960s television series "Thunderbirds". Brains is a highly-intelligent mechanical and aerospace engineer who is considered to be fifty years ahead of his time, and the world's greatest aircraft designer. A highly valued if somewhat absent-minded and socially maladroit member, he designed the Thunderbird machines and other vehicles and facilities used by the organization and its agents. He is also known to invent in his spare time; he once built a chess-playing robot called Braman. Brains' technical expertise is sometimes required in the field, in which case he usually accompanies the Tracy brothers.
