Note: The cars were sold as "10" and "12" horsepower in the UK but in Australia, the "12" was known as the "13" horsepower, presumably to increase its sales chances in a Country where large horsepower cars are the norm. It was also advertised as the 13/65 although the “65” if referring to horsepower, was somewhat optimistic if based on UK calculations. Cars were generally bodied by local builders in Australia due to trade restrictions and high import duties for complete, imported, vehicles. PEC.
