Second ?
Third a bell albino again, maybe?

Tree, I'm still learning everyday...it's why I am on the forum reading all the time. Can you tell me how you based your guessing that #1 and #3 are albino, specifically bell? I'm wondering how wrong my guesses would have been. :O
The lavender along with albino. I don't know... If you've seen hundreds of bells like I have, they just look similar to that. However, that doesn't mean they are bell.
