Numbers on old cow and calfs - Found with valueable help.

Hello

Yesterday I recived a large number of old schleich figures and so I would like to mark which ones they are, so that I can keep track of my collection. Most of them I found in the collectors guide, but I have a few I could not find.
There are written schleich in the below them and they do not look repainted, so now I hope someone is better at finding them, than I am.

I fuond two of the calves but can't find the other ones:


I can find some lying cows, but no one in this colour:


Can anyone tell me the numbers?

Wonderful finds

About the calves, perhaps TAI can help http://toyanimal.info//index.php?title=Calf

The cow is 13201 in a lighter variation, - beautyful

Thank you very much.
I just did not think that the 13201 could be that light, because I actually looked at that and the disregarded it.
The calf with the same pose as the 13110 is another variation of 13110. Thank you for the link. It was helpfull.
I could not find the brown and white one, which looks like the black and white?

All of them must be variations of colour, without special numbers. Please look here: http://www.tiewe.de/flRinder.html

Thank you Gulogulo for the link. I do not think I would ever figure out that the brown and white, where a variation on the fully brown 13005, so I never thought to look at that.
