There is some variation in the exact numbers between different versions of the kits. For some minor components, the difference lies only in whether or not they are given separate entries in the parts list, while for others there is a difference in the actual contents of the kits. The most important variations are:
Item 30, the 20 cm of string, is only included in early kits. This was meant to be used to fasten the aerial coil on the ferroxcube rod, as it is important that these loops are non-conductive so as not to act as small shorted out coils themselves. In later kits, it is assumed that it not necessary to supply something as readily available as a small piece of string.
For item 34, the wiring diagrams, the counts for EE 8/20 and EE 20 are increased by one at the same time as the above change, because a variant version of construction D 4 with reduced power consumption is added.
For items 22–24, the springs, the counts are given as 35/–/35 and 20/–/20 instead of 30/–/30 and 15/–/15 in some early kits, and as 40/–/40 and 25/–/25 in some late ones. 25/5/30 and 10/5/15 occur both in some kits of intermediate age. A UK spare part price sheet includes a set of 28 large and harpin springs and 10 small ones, indicating yet a variant count. Note that a combination of an EE 8 with 25 large and 10 small springs and an EE 8/20 with none (originating at different times or places) would lack the necessary number of springs for some constructions.
If the number of large rubber grommets (item 28) for EE 8 and EE 20 is given as one each and not three, this is only because the remaining two are counted as part of the aerial coil and ferroxcube rod assembly.
