Rod, yes I have both of those. I've finished catalogued all September build Dandenong HZ's. 107 x HZ vans. 29 of those are possible Sandmans (not 6cyl and not 3spd manual). 7 x I have recorded details off vehicles. Of the 29 possible, 2 are M40 and much less likely to be Sandman than the 27 x M20 vans.

The HZ van Adam posted up on Ebay is the highest Dandenong HZ chassis number I have recorded.
