Ok, thanks Christophe, i know both models.
I do have the first one in 2 variations, but in the 1970's plastic model.
I could have bought one last year in composition, but the seller asked 120 euro's, and he was not even in the best condition...
The other one from Lineol is quit rare, and for sure in a good condition.
Harriet, i would google a little bit around about those mini-pigs, and i am sure you can find the information you want!
