Bidoofdude's correct - only the Transformers versions had red torsos, the Diaclone version (including GiG) was black

Pics 1-3 are Diaclone
Pics 4-5 are TF G1
Pics 6-7 are TF G2
Pic 8 = MISB Diaclone
Pic 9 = MISB Trasformer
Pic 10 = MOSC TF G2

So AFAIK there's no red torso Diaclone Stegosaurus Kyouryuu Robo.
