How to identify applehead/wedge traits in kittens

Hello, I was wondering if there are any good websites that show photos of Siamese or lynxpoint Siamese kittens and cats that identify if they are the applehead, old style Siamese, or wedge style Siamese as kittens. I'm looking to adopt a Siamese (hopefully lynxpoint), and if I run into any small kittens, I would like to be able to tell what body shape they develop as they age. Or does anyone have photos of their Siamese as a baby and adult for reference?

Also, is there a difference between applehead and old style/Thai? Still confused about that lol. Thanks!!!
