Part 2 was too big so now it is Part 2a & 2b.  Hi Murphy.

The following was obtained off an internet site that no longer exists.  I have
edited and modified it somewhat to make it clearer and shorter.   For the DM
distributor model components.  See

Part 2
 
This is where the part numbering comes in. It identifies the base model plus
alterations. An assembled component would have a five figure part number code
for identification followed by a letter. The number identifies the component
as to what the car manufacturer obtained. The letter stands for changes in
Lucas manufacturing. An A would mean that this component was manufactured as
unchanged while a B means this is the same component but has had a change in
the manufacturing process. According to Lucas the component as a unit is
totally interchangeable whatever the alphabetic suffix code is as long as the
five figure prefix code is the same as the one it is to replace. For example,
the voltage regulator, as shown by Lucas with part number 37076A/F has six
different variations; 37076A, 37076B, 37076C, 37076D, 37076E, 37076F and all
are usually interchangeable with each other. Because none of the component
parts seemingly changed for 37076A/F there are only
 one component parts listing. There is also a voltage regulator 37076H and as
a unit is interchangeable with 37076A/F but it has different component parts
within it and thus has a separate component parts listing to that of 37076A/F.
Parts that made up an assembled component have a six or eight figure number;
contrast this with the assembled component five figure number. An occasional
part may have an alphabetic code at the end. I am unsure if this indicates
some type of manufacturing change.
