Boa identification help please

[Chipper]

I am trying to identify a boa constrictor. I can't seem to attach the picture how do I do it?
Many thanks

Welcome to ssnakess! Without paperwork / proper documentation we will never be able to determine exactly what the animal is, it will always be a mixed blood boa. We might be able to recognise the main influences. You can upload pictures after 5 posts!

I know this is probably a stupid question but what papers normally come with a snake?
