There do seem to be quite distinct shades of primrose, the lighter of which some call pale lime green. Like the 226 shades of pale blue, however, I am not sure whether there are two colours or a range running from one to the other extreme. As adding another colour would mean an extra four rows I have decided, for the time being at least, to list just 'primrose'.
I had previously listed the free-spinning wheel editions as having a type 2 base but I believe that nearly all would have a type 1b base. I have seen this example of a type 2 base, however, but it has only been the one and I am by no means certain that it will have occurred more than very rarely across the range and so, at this stage, I have omitted it.

You will find racing number decals of 1, 3 and 7 on all colour combinations and the digits have two clear types - a thick style and a noticeably thinner style.
For an explanation of the different types, please see my article titled Minis - the different types in September 2017.
