Hi David, I agree there is nothing wrong with a good debate about this.
Ours has the Schleich Emblem and was bought in a huge lot about 5 years ago so was very cheap.
Personally, like Fram, I have never really considered the red trouser variation as a "rare" find as I have seen him sold so many times right from when we first discovered Ebay. I will certainly look for some kind of "proof" but as we know, so many genuine variations have not been documented by Schleich in their catalogues and guides that this could cause difficulty.
You mentioned the blue skipping rope, I have to admit, I never thought that was a genuine figure hence why I never bought one but the points that you make about the numbers of her being around are very valid.
The issues of faking smurfs and what is or isn't genuine is certainly a big problem and is going to cause even more controversy in the future I am sure but we do also have to remember that there are many many genuine variations out there to be found and even a few honest collectors / sellers.
