Let's try to make a list of all "World of Nature" specials - singular models (not in packs) - that are not in Schleich catalogues all over the world. These are the ones I know of at the moment:
1. brown pelican 14173 - only featured in USA catalogue 2000 (and later/earlier?)
2. hereford bull 13763 - only featured in USA catalogue 2014 (new that year)
3. hereford cow 13764 - only featured in USA catalogue 2014 (new that year)
4. hereford calf 13765 - only featured in USA catalogue 2014 (new that year)
5. black angus bull 13766 - only featured in USA catalogue 2014 (new that year)
6. black angus cow 13767 - only featured in USA catalogue 2014 (new that year)
7. black angus calf 13768 - only featured in USA catalogue 2014 (new that year)
8. ...?
Anybody who wants to help complete this list?
