None of the NAMC’s “Catalog of all Series Matchbox Models” (first edition), the AIM “1-75 Series Regular Wheels” catalogue (second printing, 1983), Houghton or Stannard contain any unlisted variations.
U.K. Matchbox covered the model in Volume 4, no. 3 (Aug. 1980) p 96, and notes that the military version (Nick's variation codes 14 and 15) comes with either turquoise or dark green windows. Since it appears that bodies 3 and 4 together form a twinned mould, this window colour variation, if accepted, would inevitably give rise to two new codes at the end of the table.
