Great surprising find.
This is how I found my handy/mechanic Smurf with purple overall, back then in 2008.
(This one :

It was on an online second-hand shop, from someone who sold a bunch of common Smurfs. The whole lot costed me around 20 euros, I got around 30 Smurfs and the Smurf farm building.
The picture that was uploaded, was small and nothing detailed, but I could see him standing in the group of Smurfs. So I bought.
All the rest was sold on eBay again for around 2€ each, so I even got profit more :-)
And the purple overall mechanic, he stands in my collection. So if someone has the one in an orange or blue overall for sale, I am interested ;-)
