Thanks everyone for your responses, much appreciated. We have decided to engage the AOMC and are now waiting for them to hopefully provide us with the history.
We have since discovered a serial number on the VIC rego papers, we are not familiar with what a serial number is as we don't have them on the NSW rego, could this be the chassis number or is it indeed the number written on the firewall.
My father has the book ''The History of Holden since 1917'' by Norm Darwin, is this the same book you are referring to? as I'll need to import it from Tassie to read it :-)
Would it be a bad thing to dress it up as a staff car?????
Thanks!
