The NAMC’s “Catalog of all Series Matchbox Models” (second edition) suggests the MW version comes in three distinct colours: light green (variation code 21-2A), medium green (variation code 21-2B), and bluish-green (variation code 21-2C). Can anyone confirm?
The AIM's “1-75 Series Regular Wheels” catalogue (second printing, 1983) does not list any variations not already recorded by Nick, and neither does Stannard.
Houghton notes that early models have a matt black baseplate whilst later production uses gloss ones. The changeover is listed as occurring during Nick's variation code 3 (green, GPW, d/h, c/a) which can have either a matt or a gloss black baseplate.
U.K. Matchbox did not examine the model.

Please note that there is also an unlisted early casting variation (c.f. 10c and 46a), and that two variation codes have been found with gold trim.
