When Bordesley Engineering closed in 1926 Bert Perrigo moved to BSA and joined the competitions department. His
motorcycle trials success was important to BSA and they developed the
BSA Blue Star range with help from Perrigo, who was paid one-half-penny royalty for every Blue Star sold. His first major commercial success was in 1937 when
Wal Handley was presented with a
Brooklands Gold Star for lapping the circuit at over on a 500 cc
BSA Empire Star. Any rider who achieved a lap during a race was awarded a "Gold Star", which was a enamel badge a small square on the bottom of it which said "100", but Perrigo saw a good marketing opportunity and persuaded BSA bosses to invest in the development of the 350 cc and 500 cc
BSA Gold Star which became a top seller for BSA for the next two decades until 1963. Perrigo was rewarded with promotion to become the Chief Engineer and Works Manager of the BSA Motor Cycle team. Perrigo also led the BSA
Maudes Trophy when three BSA Stars successfully completed the round Europe tour. ==Racing career==
