What model Sandman is this?

[TwoTees]

If it is a Sandman the MODEL is easy, it is a HOLDEN (or Belmont if it is a modified HQ). You couldn't get a Kingswood Sandman van. So MODEL is M70 (or in HQ: 0170 or 0270).

The Question you want is what SERIES is it?

If it is factory original or factory authetic then it is obviously HX or HZ by the tail-light surrounds and mirrors. Dead giveaway is the lack of an RTS badge on the tailgate, and I can't quite see a chin spoiler on it. It does appear to have a Kingswood front bar on it so it isn't dead stock original. So all that adds up to is a HX with Kingswood front bar.

Byron,
You can't see the forrest for the trees.
