It was a genuine question 'though
You can tell it's a G2 because G1 steels have more disc-separation inside. You can see the bottom spindle like here -the pictures in post #10 should answer your question, practically just right above your post...
... and side by side with the G1 FAST AND FURIOUS 1 - 4 PIMP MY RIDE stickerbook should banish any doubts:-Thanks a lot.
I feel stupid now, but I learnt something and that's always nice
I looked at the pics (obviously) and I did lots of researches on the net to be absolutely sure and yet a doubt always remained... anyway thanks again for your help!
