in need of some opinions on this van

[kaido17]

hi guys i have came across this van which im told is a genuine hz sandy L31 with original motor and chassis, i am still waiting for an email with the tag info but it looks to have all original interior and full hoodlining aswell as black door handles and so forth,has some rust but i think will make a good project as its been offered to me for only $4500, i need some opinions on if it looks to be a genuine sandman, will post some pics of the tags as soon as i get photos cheers
