Ok mate I got this...read the print and you should be able to locate a book maybe?? still looking...I know this is a lion but I saw a Tiger as well...bear with me.

cheers bullet

I also found Eliot Goldfinger has a book called 'Animal Anatomy for Artists' try that and I found this..no Tigers but it may get you going in the right direction?
