hq sandman?

[HK1837]

I'd only ever head it. It can't be 100 total. Must be the initial run of Sandmans (possibly 1-3/74 build).
I have:
1 x 1/74 build Sandman, Acacia Ridge van (this is the L31 M21 Saffron one i've had for years).
4 x 2/74 build Sandmans or possibles recorded, 3 x Acacia Ridge, 1 x Elizabeth.
24 x 3/74 build Sandmans or possibles recorded all Elizabeth and Pagewood except for 1 x Dandenong and 2 x Acacia Ridge.

Plus the pilot/prototype from late in 1972 (a Kingswood ute).

They are all 30, 39 or 35 trim other than the 10E trim on the pilot.

There are only dribbles of them after that, apart from 16 in July 1974:

7 x 4/74
9 x 5/74
5 x 6/74
16 x 7/74
6 x 8/74
2 x 9/74
