The '109 camouflage scheme shown was carried on with the 'F' and early 'G' models, before the introduction of the time saving 'simplified' scheme, which in turn gave way to an even more simplified, soft edged scheme. The original asymetric pattern was designed to add to the disruptive effect of the splinter pattern, and was very effective. This scheme was gradually replaced in order to save on production time and materials, as well as being part of the 'development chain' of camouflage in general.
Interesting point about some aviation 'historians' bad-mouthing modellers Matt. It is often the case that a modeller is a historian (or at least amateur historian) first, and modelling is a logical progression or 'off shoot'. In many cases, this can mean that the dedicated modeller, striving for accuracy, can know more about, for example, the background of the subject, it' s operational use, units, crews etc etc, than the so-called aviation 'expert' wil ever know!
