Lucas Part Numbers

In the early 1980s Lucas was using three sets of part numbers.
Engineering Numbers
Part numbers such as 54419946 and 35057.
Trade Order Numbers (TON)
CS2 and 8FL43 etc
International Catalogue Numbers (ICN)
Like DSB 752 (contact set two) and DSB 752W26 (contact set 2 workshop bulk pack). This seems to be intended to make a more rational version of the TON. The basic number is three letters and three numbers DSB 101. The first letter is the product group, the second is the type of component, the third sometimes give important information such as nationality of the device. Really. DSB 1** is for a Lucas distributor. DSB 2** is for French Distributors, DSJ 1** for Hitachi Distributors. Britain seems to have been suffering from an invasion of illegal immigrant distributors.
