Just so you know "only Brisbane built" Sandmans have the option code XX7 or XU3 etc on the tag.
All Sandmans built at other plants didn't mark the tags with these option codes. That's not to say you couldn't have the option pack, it's just it wasn't stamped on the tags.
Sandmans from plants other that Brisbane are just as much Sandmans the ones from Acacia Ridge/Brisbane without the ease of tag identification.
