All the figures in this set are appropriate for the weapon to hand. The first man is looking at the potential target, the second is feeding ammunition, and we have two gunners controlling the weapon plus the driver of the tractor. For most of these, however, there is not much else you can do with them except that for which they were intended. Much the most useful figure is the man scanning the skies with his binoculars, who could be in one of many roles such as the Royal Observer Corps for example.
The three seated figures are all quite thin and weedy, since they needed to fit their respective seats, and while the two standing are better, all have a fairly poor level of detail. Indeed it is hard to make out much detail at all, so pockets on the battledress are almost invisible. The 'tin hats' are a bit better than in some kits, but nothing here really looks good. The three sitting figures have mould marks on their backs, and the man with the ammunition clip will need a base as he is meant to be standing on the gun itself. Our example was relatively low on flash and with no sink holes, but this can vary between batches.
Although this set has been around for many years, Airfix have never included an illustration of the model itself in any of their catalogues.
