We used to Tank them around the world with the Valiant. They climbed at our rate, cruised about 2 kts faster but could out descent us by miles. The Gloster Dragmaster was one name for them. They had a cartridge start system which frequently failed.
I remember brining one back from op Shiksha, a co-operate with the Indians, which had lost its Nav from an ejection over the Jungle [fortunately he survived] and was so bent after recovery from a spin that it flew sideways.
