The group later built itself around a new champion in Shirley Crabtree, a young bodybuilder who won the title after it was vacated by Assirati while injured in 1960. The BWF faded away in the late 1960s after a campaign of pestilence by a disgruntled Assirati (vastly superior as a shooter to Crabtree) in the form of unsolicited appearances and challenges to his successor at BWF shows, eventually resulting in the abrupt retirement of Crabtree in 1966. Lincoln's own promotion was bought out and amalgamated into Joint Promotions at the end of the 1960s.
