I just found when the B47 headlining was added. It was fully signed off on 14/8/74 (the day I turned 7!) and was issued on 27/8/14. Expected cost was $4.52 per vehicle. So the very first few HJ Sandman vans probably didn't have B47 incorporated. Certauinly the publicity shot vans wouldn't. If you look closely at the red van on the HJ Sandman brochure it looks very weird in the headlining area. This is more than likely a Dandenong HJ first build so may well be the same van with a dodgied up headlining.
