Actually Stuart, Diana has a point.
If we continue to use the wrong terminology for a vehicle, then it will continue to be cllled the wrong thing by newcommers, new generations etc.
On REMLR I have always tried to be as acurate as possible as many people look at REMLR like an online reference book, expecially the ARN database. As such, if I didn't have definitive proof such as paperwork of some kind, or a whotograph showing indisputeably the information, then I put it in, if there was some doubt, it was either filed for later collaboration, or included with a note that there was doubt in some form or another. As such in recent years I have been far more careful about referencing the source of photos an information in a similar fashion that the author of a book would have to do. Not quite to the same level, but I am continuing to improve. Many thanks for that go to Mike Cecil for pointing out my lack of referencing, which in any research field is unprofessional at best, or negligent at worst.
So if we keep calling them ACCO's, that misnomer will continue to pervail. Hence why I try and refer to them by their proper titles.
Census codes are another example, few census codes refer to just one vehicle, they refer to a vehicle type, for example, 6028, the 3/4 Ton GS, refers to Landcruisers, as much as it does series 2, 2a and 3 land rovers.
In the case of the line that started this debate, "TRUCK 2 1/2 TON INCL DUMP" I would have thought that meant that it was 2 1/2 Ton Trucks INCLUDING Dump, so it would refer equaly to the AB-160 as it would the Mk.3.
