King's Cup 1980 Finningley

I logged G-BAVE (possibly incorrectly) at the 1980 Finningley Air Display where the King’s Cup Air Race also took place, but this may be a typo as I had it down as a ?Cessna whereas, in fact, G-BAVE was a Beech A100. The only fact that I’m sure of is that it carried the race number 9 whatever type or registration it was. Can anyone help please?
