Hi All

New to the forum and the sandman world. I generally play with holdens a bit older than the 70s, typically FX-FJ. I came across this van by chance the other day. I am interested in looking to purchase it, if it is a sandman. I have taken some photos as shown below. The tag details are:

Model HZ8W M 70
Body No 399945-A
Trim 1930-18V
Paint 568-30521
L31 M21 (hard to read) GV4

HZ Panel van
12/77
AHZ 08274S (with matching chassis number)
GVM 2000
Seating Cap 2

8M70THH9412877

It is white but looks to have a grey colour underneath (?)
The body is very rough. Im not familiar with where these vans typically rust but apparently on this one its everywhere... The top gutter, the seams, sills, doors etc.
It has a hoodlining that runs all the way through to the tail gate.
Unfortunately they have misplaced the key so only got to look through the window.
It has a mod plate for a bench seat.

A couple of questions:
Is it a sandman?
Are the rivets on the tags correct/original? (they are different to the 1950s)
Are the side windows original? They look very similar in dimension to others I have seen photos of on this site and others.
The age old question of value..... While I would like to get it cheap, I dont want to steal it if they dont know what it is.. I realise this needs a ton of body work (Ive got an FJ van that is in similar condition). It does look like it has a few bits and pieces though not sure yet how much is ridgy didge (read novice).

Any help would be appreciated. Something with a bit more grunt than a standard old grey motor would be nice.

Cheers, Andrew
