Upton Tractor Details ?

Hi Guy's - I recall details of an Upton Cummins powered tractor sitting around/waiting to be rescued.
Anyways I've been in contact with the Upton family who built these great Aussie machines & they're looking for the whereabouts/history of survivors still out there - much appreciate any leads & please PM me with details.
Thanks.

...Fortunate Son or Acar put up a pic of one of these laying around in SA.... it was on the ''Autocar Adelaide'' thread on the forum around August 2012....(google is your friend!)

I'm fairly certain there's an Upton (or 3) in amongst all this..
