FTO13 Fantasy Tribe Orc Wyverns

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