The Birrana A78 was built by Malcom Ramsay using 273 and 274 components for Ramsay to contest Rothmans Series events in Malaysia in 1978. Ramsay finished second in the Penang Grand Prix and the Selangor Grand Prix and third in Malaysian Grand Prix and was leading the series when it was cancelled. The A78, which was the last model to carry the Birrana name, was later sold to John Holmes of Queensland as were all Birrana patterns, jigs and dies.
