Do you think this is a HQ sandman

[HK1837]

It could be a Sandman, but you will never know for certain by those ID plates alone.

If it still has its original body the seat separator mount (also used for rear console screw) is the only way to pick a HQ Sandman van.

Tyre placard and door switches are no help in HQ as Mauser has already said.

The trim has been changed at some stage if it is black. 39B is brown with bucket seats. Mauser, Chestnut is the Kingswood name, on Belmont 39 is brown.

I just stuck it in the database, and I have another Sandman, 2 x digits lower than this one in both VIN and BODY numbers. It has 39B trim too. It is 34 x numbers lower in the chassis number though and I think at Elizabeth this is a better indictation of where they were on the assembly line relative to each other. It appears that whomever was doing the rolling schedule for Elizabeth grouped cars by colour and/or trim so I bet the car in between these two in BODY number has 39 trim as well.
