The B35 VH-KWK was operated by KWK Transport out of DB in the late '60's.
They had a Baron as well, but don't recall the rego. but was KW?. Kevin Kent was the front figure in that operation.
I recall the company was sold to TransWest Air Charter (TWAC) around that time also - TransWest and Aerial Enterprises were the only charter operators in DB in 1970.
Great days - they even had Flight Service !
