The most recent example being the Recoil 3. This fine example initially became the least ever altered, such was the quality of its design. However it did soon become the very first Scorpion and later the Jaguar.
So how old was it? The carcase lives on to this day but the major organs and their configuration bear little in common with their ancestor - the Recoil evolved!
