MW comments on 18/01/2012: The A Series was only ever produced in any number in Articulated Tractor Unit form. There were a few A Series draw-bar four wheel (two axle) rigid lorries built, but the vast majority of four, six and all eight wheel rigid ERF's retained the pre A Series (LV) chassis technology, although some shared the 7LV A Series cab. The LV in all forms, even tractor units, continued in production alongside the A Series until the introduction of the B Series in late 1974.
Many show organisers, and indeed owners, do not actually know the difference between an ERF LV and an A series. Most assess the model type by the cab fitted, which is possible with ERF KV's, The earlier LV's, B Series, C Series, E Series etc, but the A Series referred to the Chassis technology, not the cab.
