Released in 1982, there were two versions, the first, shown on a 1982 flyer, had a one piece wing and no saddle for the rider. The later one had a two piece wing that slots through the body. It is possible that the second version was only released in the US.
There are several head variations for the rider, as was common in the Fantasy Tribe ranges, see the CCM Wiki FTO13 section for details.
