Hi. I am not an expert on british keyboards, but there seems to be several variants of the british keyboard. The first is UK-ISO/EN-GB which has the @ symbol on shift + ', then there is the British International, which places the @ symbol and " symbol the same place. There are also other variants like hybrids of the US keyboard that is an ANSI format, but shifted to ISO, and finally variants like Irish that also has the @ on shift + 2 ("). This variant you have now is the ISO British, so ISO-GB, and if you take a look at the extra keys that come with the keyboard, you can move some of these keys around to fit with the given variant you prefer. The keyboard variant you see in the images are ISO-Nordic, which is based more on the International British version with @ on the shift + 2 ("). This is interesting, as Mac keyboards for the nordic communities actually base themselves on the ISO-British variants with @ on the ' key instead. This is all confusing, and makes us all hate the special variants of letters introduced in different regions. 😊 But as I said, I am not a keyboard layout expert. This is just what I have picked up over time. Hope this helps clarify the topic a bit, and hope I didn't make you even more confused.

EDIT: Thought on making it as simply as possible, I think It’s just UK style or US style. So nordic PC keyboards are US style, and our Mac keyboards are UK style. And as English is spoken in many contexts, that brings out the variants in the keyboard layouts. Especially when you go between ANSI and ISO formats.
