The Airfix kit came out in 1977, just like the Heller kit. Its quality is typical Airfix, raised panel lines, quite a few rivets, and few parts. It is some 2-3 millimeters shorter than the Heller kit, which is quite noticable for such a small kit. A nasty problem of the kit is that the armoured windscreen is moulded integrally with the canopy (see the 1984 box-art). Replacing both is about the only option to solve this problem. The model was sold in at least two different boxes plus a blister, as shown on this page. After the excellent Academy kit came out in 2000, it is only worth buying if you're a model collector.
The photo below of an Airfix Komet model was sent by Marius van Aardt from South Africa. Quite a convincing diorama shot! More photo of this model are shown here.
A photo of a built-up Airfix Komet can be found on Skitz Fijan's site hosted by Pedro Freitas. Note that White 10 is a Heller model though.
