The Natrix natrix natrix doesn't have those half-moon-shaped light-coloured markings at the back of the head beginning of the neck. It's just plain dark coloured on top and light coloured underneath.
It was Daniel who explained to me thet the N.n.scutata looks almost exactly the same, except for those markings.
When chasing down pictures on the internet, I found that often Natrix natrix subspecies are not identified, so it took a while. Apparently Natrix nartrix natrix is less common than the other sub-species, which may be why they require extra paperwork to obtain.
I am not certain which sub-species Dan is planning to bring in.
I sent off an email to him with enough questions to keep him busy all weekend.
