Maureen,
I will try to explain this as simple as possible, since I know you are hard to convince!!
On the first picture in this thread you have all the smurfs Bully made. Starting 1973 and stopped in end of 1979.
These are the only ones. No more no less.
When Schleich got the worldwide license 1 january 1980 they got all the Bully molds.
And since Schleich wanted to sell these ( and probably also get back their own molds made between 1965 and 1972, which was in Bullys possesion) they added these in their 1980 catalogue.
So all smurfs with articlenumbers 20001 to 20067 are all the smurfs Schleich had made until 1980.
So when they added the Bullymolds the numbered all of them 20068 to 20121.
BUT there were 4 of the molds that did not get any articlenumber. Bullys version of Astro, Smurfette, Digger and Gargamel.
If you think of this in buisnessterms. Why?? Always, even today, if you want to sell something you give it a articelnumber. Schleich always do so.
The only reason I can think of, for not giving them any articlenumber is if they were meant to replace their own versions. But they did not. They sold their own versions all the time after 1980.
And for example for both kicker and tennis they kept their version and gave the Bullyversion a new number. So if they wanted to sell these they would have given them new numbers.
So here are the facts about these 4.
They were never given articelnumbers by Schleich.
I have never seen any of them with Schleichmarkings.
I have never seen them in any Schleichcatalogue.
I have never seen them on a Schleichposter.
I have actaully never seen them with any traces what so ever that could link them to Schleichproduction, painting, selling.
etc etc.
So if you check a poster from around 1984 with all smurfs pictured, you would probably end up finding all Bullymolds except these 4.
Not sure this poster is from that exact time but I think you understand what I mean.
