Association Of Road Operators Car / Lorry Badge 1

A R O Association Of Road Operators Car / Lorry Badge. 157 mm (6.2") tall. The ARO was the forerunner of the Road Haulage Association. This is an early alloy version of the ARO badge and is the only one of this type that I have ever seen. The slightly smaller chromed versions are also considered very rare. Nothing known about this club, any information would be very welcome.
