Two vehicles R06101685 and R06101686 just before yours were the first two CKD to A&T the whole lot probably arrived on the same ship to the Port of Brisbane mid November. I have a batch R06101825 arriving in Port Jackson 12/12/49
Have started a CKD list in the other A&T thread and am adding approximate arrival dates
Do you have the original firewall? If yes, the Important info plate was affixed to the right of the steering column, so there would be four screw holes. The long annand and Thompson plate was in front of the passenger, so there should be two holes for that if present, although the Rover Co Ltd plate was often affixed in the same location on the 1950 models.
