5a London Bus

[Idris]

None of the NAMC’s “Catalog of all Series Matchbox Models” (second edition), AIM's “1-75 Series Regular Wheels” catalogue (second printing, 1983), or Stannard, lists any variation not already catalogued by Nick. Houghton notes the green version (his variation code 5a-4, Nick's variation code 1) as having no recess and an angled top whereas Nick has the opposite, i.e. with recess and square top.
U.K. Matchbox examined the model in vol. 1 no. 7 (Sep. '77) p106 (reprinted vol. 4 no. 3 (Aug. '80) p88) with a follow-up in vol. 1 no. 9 (Nov. '71) p141, but no variations not already covered by Nick were identified.
