Attached are some pictures of my Dad's C60L.
The exhaustive search of the ARN books in the War Memorial finally paid off when we recently found the ARN for this truck
73446.
My Dad has driven this Blitz to Corowa for the past few years and is looking forward to bringing it there next year with it's ARN painted on.
