The NAMC’s “Catalog of all Series Matchbox Models” (second edition) lists as variation 19-2A a cream model with MW, c/a, silver trim, without column. I would suggest that this is almost certainly the result of a driver swap/replacement. All models are listed as cream except for variation 19-2F (MW, c/a, silver trim, with column) which is catalogued as white.
The AIM's “1-75 Series Regular Wheels” catalogue (second printing, 1983) lists variation 19-2C as being GPW, c/a, gold trim, with column. This variation is shown by Nick on his catalogue page, but is missing from the table. AIM also notes that "...the colour of the body varies from white off-white to creamish...".
Stannard does not list any new variations, and neither does Houghton who, interestingly enough, differentiates the two driver castings as without or with jacket (corresponding to with and without steering column respectively).
U.K. Matchbox did not examine the model.
