When Class numbers were introduced they were initially split between Class 105 and Class 106 depending the the engine they had: AEC engined vehicles were Class 105; Leyland engined vehicles were Class 106. At this time sub-classes were used as were different class numbers to differentiate non-powered vehicles. All was simplified in the late '70s when thay all just became Class 105s.
In later years, the 50xxx vehicles were renumbered into the 53xxx series, as were 56xxx vehicles which became 54xxx. This was to avoid clashing with Class 50 and 56 locos on TOPS.
The NE prefix was only carried for a brief period by some vehicles.

Generally vehicles stayed in their original formations until about 1971, but by 1975 this was the exception rather than the rule.
Worksplates were carried on the vehicle solebars to identify the builder and lot number. Many of the worksplate images on the website are by Simeon Gaskell.
