The title of 'Air Force' is rather grand but also rather vague. Without knowing the contents of this set it would be easy to imagine a long list of possibilities. However the actual contents would probably not feature anywhere on that list.
Basically there are two components. First is a helicopter, or perhaps a gyro-copter, an extremely light one-man machine where much has been left to the imagination. The cockpit is of course without its glass/Perspex shell, and the pilot has no instruments apart from the joystick. The instructions on the box indicate a rear blade - essential for stopping the helicopter from spinning, yet that part has been lost before final production, and the end result is a much simplified model. The machine stands with the blades approximately at head height, and when the pilot is seated in it his head is alarmingly close to those blades. One possible inspiration for this model might be the Dornier Do 32, and it does share many characteristics, although obviously still greatly simplified. In any event the Do 32, which was developed in the 1960s, never went into production.
The other piece could well be described as the exact opposite of 'Air Force' as it is a surface-to-air missile. This is also very much simplified, and does not much resemble any existing weapon of the time. A device at the front allows some variation in elevation, but at full height it is well over twice the height of a man. Sadly it comes with no crew at all.
On the sample we considered, this set had a great deal of flash and took a lot of trimming. In some cases the holes were too small for the pegs, so again some careful filing was necessary to make the models fit together, though better too small than too large. Each sprue comes with two of the pilot figure, though only one would find space on the helicopter. The other man is waving his paddles about but seems to have no particular relevance to this set. The style of sculpting on the figures is not one of our favourites, and detail is shallow and poor with mould marks making matters worse.
It is hard to see what interest this set would generate today. As a toy, which it was created to be, it is fine, but modellers would be looking for much more accuracy than this set offers.
