I'm new here but post occassionally on other forums.
Interesting threads.I love variations in the vintage line and the Chewbacca green limbs one is always a good way to start an argument.
I have 2 Chewbaccas with the exact same copyright and placement as the green limbs one shown in the post above with Hong Kong in small lettering etc.
One has green limbs and the other is brown with no hint of green at all.
If they came from the same factory then presumably they were produced at a different time and that the green limbs ones were a batch made from a different plastic grade.Certainly it's not a case of all with this copyright having the green limbs.
I don't believe it's discolourment on these Chewbaccas as i remember someone saying they'd cut a limb in half and the colour was constant right through.Others swear that theirs came like this off a card too back in the day.
Anyway just my 2 pennys(i'm from the UK
) or cents worth.
