Colombians are the most common Bci locale in the pet trade, but he looks a bit more like a Colombian crossed with a darker locale, perhaps something like a Nicaraguan or a Tarahumara mountain boa.

Like I said, there's no way to determine locale for sure, but he's a beautiful boa! I love the belly speckles.
This is absolutely correct. It is a Common Boa Constrictor (BCI). Not a true Red-Tail (BCC). You can tell for sure by the tail - a BCC would have solid bright red tail saddles. Once you see one, there's no mistaking it.

I agree that it looks like this snake might be a columbian crossed with a nicaraguan, but there is no way to know for sure unless the snake's breeder could provide documented lineage. But that belly makes me think this might be so.

One thing is for sure, it's a gorgeous snake!!!
