Looking for registration history of an Alfa 33

[davelim8850]

Looking for the registration history of a red (from factory til now) Alfa 33(905) 1.5 QV (1985). Bought it from a guy in MOrdialloc who had it for quite awhile ( never registered it) and had bought it himself as an unregistered/dereg car from an elderly chap called John (now deceased). Car was supposedly registered in VIctoria at some stage in its long life; but records using the VIN and engine number not found in VIcRoads. Pur.Sang (now Maranello Pur.Sang) cant find records unless I have the original registration number. Their dealer sticker is on the rear windscreen. ANy clues appreciated.
