This is another of those well-loved building accessories that Airfix used to produce to give your model soldiers a place to attack or defend. Originally it was called 'Jungle Headquarters', but was later renamed 'Jungle Outpost'.
Along with a fair few accessories they also included a couple of the above Japanese infantryman leading a pack-horse. The man is nicely done and authentic (an improvement on the much older Japanese infantry figure set), and he wears his field cap with sun curtain. There is very little flash and the detail is quite clear. He has been given pegs on his feet and a separate base for some reason - perhaps the base which was originally supplied with this building (but is missing from more recent issues) had holes in it to take his feet, giving the modeller some flexibility. Happily Airfix learned from their early disasters with pegs in bases and here the pegs are a good size and fit securely.
The man is leading his pack-animal, which again has pegs on its feet for the separate base and again this fit is very good. The animal also has holes to allow you to attach some baggage like that shown, and the whole thing is pretty useful, with potential to serve as a beast of burden for quite a wide range of periods we would think.
Although this product appears in a number of Airfix catalogues, it was never made up and photographed, so the above artwork was always used in one form or another.
