Is that the same Mike Courtney, who ran Austin Seven sports - 1930 type seven, and also owned for a while a rear engined single seater with a Standard Vanguard / TR2 motor, think was called the RA Vanguard. have a photo of the engine somewhere but not the whole car. Mike lives / lived in Oratia / Glen Eden area in the late 1980's on some acreage and a big shed for cars, with a 1920 Villa brought from Mt Eden placed on it.
