I got the same KO number info from the seller.
They all appear on The Register.
KO 063 (red), no pics, listed in The Register as beige in Brisbane, QLD.
KO 193 (white), pics, listed in The Register as beige, in Perth, WA.

It would appear there has been a shuffling of vehicle locations since recorded in The Register. All these CBs, according to the Samba ad, are "West of Sydney". When you think about it a bit, almost everything in Oz is somewhere "west of Sydney".
😂 It's a long way from Perth to Sydney, so that's a little puzzling how KO 193 got to the east coast from its recorded Register location. Also, it's a little odd, but there's no asking price on any of the CBs. There's really not much in the way of substantial information about any of the cars in the ad. The seller is incorrect about his US count. There are 11 CBs in the US, and supposedly one in Canada.
Another interesting curiosity is that the seller's location is listed in his Samba profile as being in California, USA. So, how is it the vehicles are in Oz, and the owner is in California?

In one of his other Samba ads, the seller states he was raised in California as a child, so everything seems a little mysterious to me.
