Must be a new one since I told you what I had last. It is an Elizabeth 3/78 18V XX7 van, in L31 M41 GU4 spec (I don't record where the ID came from or when simply so that the database has no references to any personal or vehicle location details). The non-Sandman is a 4/78 63V Kingswood ute in L31 M21 GV4 spec. Yours is a "series II" example as it has Commodore trim (I'll stop calling them series I and II HZ or it'll be all over Ebay in no time like you see with HK Monaro and GTS!).
