dang I think you're right. i had a vatf before at about 5" and it's head looked bigger and the shape of the body was taller and shorter like the pic in the link you provided.
The 2 I got have small heads and longer slimmer bodies. I'm kind of bummed out, spent $90 and the lfs guy is really cool. I'd hate to go and say I want my money back. It's not his fault tho, his supplier said they're vittatus.
