[souffle]

On looking at those sideways pics I think he may be actually banded rather that dominant spot as there is a stripe of white up his side then a blotch on top all in the 'band' area. As his belly appears to be white I'm pretty sure he does have a pattern there and I think he's a version of grey. He doesn't look like a tiny baby to me. I'd say about 10-12 weeks.
It is hard to tell when you can't see them in the fur so to speak as they can look very different in different lights from photos.
