HJ Sandman information

[HK1837]

I think the N70 on the header is a mistake.
I have the armrests penned as either a 5/75 or 10/75 change to component option, POA document has revs on 5/3/75, 15/5/75 and 15/10/75 so it must be May. It could still possibly be October but i'm pretty sure that revision is for XU3 and XX7 introduction into production. Another change date nailed!
B47 is comfort pack on HJ-HZ (B30 + BB7). Very rare as it would have been an expensive option, and it was the only way to get factory carpet in a van (B30) if it wasn't already standard. My guess is dealers just put in aftermarket stuff or got genuine carpet and fitted it, hence why you don't see B47 outside of Sandman or Kingswood van.
