There was a Drover based out of Berwick, Tyabb or YMMB around about 1987 or so, seemed to do the airshow circuit for a while.
That was VH FBC a mk3 version (i think it was the last drover built)with the lycoming engines. It was purchased in NZ and ferried to Aus by David Squirrell and Brett Young. It remained at Berwick for a couple years before being sold to the powerhouse museum. i believe it is now on display at the museum in bankstown. As a kid I was fortunate to go for many a ride in this aircraft when it was at berwick.
