Released in 1982, there were two versions, the first, shown on the 1982 Orcs and Samurai flyer, had a one piece wing and no saddle for the rider. The later one, shown in the 1983 US catalog, had a two piece wing that slots into the body. It is possible that the second version was only released in the US, the spear seems to have originated there.
There are several head variations for the rider, as was common in the Fantasy Tribe ranges, see the CCM Wiki FTO13 section for details.
