As I have said before it seems many of the smurfs Schleich made in late 70s and around 1980 seems to have been made to fit very well for promos. Eventhough not always having printed companynames. For Australia I have written about the Smurfee and VFL variations.
But when you check the markings on some of the smurfs Schleichmade these years it seems they must have been made before showing up in catalogue.
First versions of cleaner, ice lolly, first aid, cardplayer, thirsty, champion, toothpaste, rugby, congratulations, pommes etc could all have been made to fit special markets ( countries) or companies in the beginning.
Thirsty for example have very strange marking.
I got a collection with early variations of tennis, pommes etc and noticed the colour of the material on the plug that was the only thing left on the thirsty. It is brown material.
So do you think it was a brown bottle in the beginning or a promo?
