Both PB ranges were based on Phil Barker's books Armies of the Macedonian and Punic Wars and The Armies and Enemies of Imperial Rome. This figure is taken from illustration 76 in the first edition of AEIR.
The code numbers for the AEIR range correspond to the illustrations in the book plus '100', i.e. illustration 1 is figure 101.
The base is numbered PB 176 on the upper surface in the usual manner.
