Of course the Klaas factory could use different type of runes, and there may be some variations not pictured in the book. There can be some things even best authors don't know about. But: few years ago I got burned twice buying fake SS daggers (one of them had the same looking runes). The second thing is when I see fake SS daggers, they always have those "non-textbook" runes. See the attached pictures of confirmed FAKES. Would you be also so positive about dagger with such runes? Some another unknown variation?
I haven't stated that dagger of our welsh friend is a fake. It's JUST ME who wouldn't buy it. If I'm into spending few thousand $$, I prefer to buy something unquestionable.
