13a Bedford Wreck Truck

[Idris]

None of the NAMC’s “Catalog of all Series Matchbox Models” (second edition), the AIM's “1-75 Series Regular Wheels” catalogue (second printing, 1983), Stannard, Houghton, or Leake ("Concise Catalogue of 75 Series Matchbox Toys by Lesney" (4th edition, reprinted 2006)) lists any variation not already catalogued by Nick. However, AIM does note the existence of two distinct body colours (listed as tan and dark tan).
U.K. Matchbox did not examine the model.

A large number of variations were highlighted in and older topic. These included two degrees of infill behind the cab, the existence of models with d/h c/a (one of which has been found with a maroon jib), and and a model with an orange/red jib.
Antonin's variation table is reproduced below.
