Great news - we got another van on eBay last week. It's not in great condition but it's a rare find - a van with sliding back & front windows + a backseat. The compliance plate shows that it was a van, and it's serial number is #725 - given that
BMC started the numbering at #501 this means that it was probably built in the first month of production in 1964 (according to
this great article from the Mini Experience). We thought that this was a Traveller, but
Craig Watson from Mini Experience let us know that they didn't make any factory Travellers in Australia, so it's most likely a dealer fitted modification - more detail when we pick it up and get it home.
The lichen is a good look!
