He looks very very similar to the 'yellow headed albino' in the Barker and Barker Ball Pythons book, but I can't tell if they have solid yellow heads, or just lots of yellow.. lol. Can't find much information either, and don't know enough to make the call.
Got him cheap bc the guy's habitat malfunctioned and he got a nasty burn near his tail. It's shallow and will probably go away after a few sheds, but it doesn't look pleasant. The guy wanted to sell him to be able to afford a better (and safer) rack for his females.
Edit: oh.. also just realized first post I said he was 1300g... weighed him today and he is 1627
