Small piece of paper in grip/mag well

Someone other than a German could have written it who was in the service of the Germans could it not? Did all Euros make the nines the same way? Can you be sure?

Yep, most likely somebody else than a German, and:
after 1945.
And hidden underneath the grips? Come on....
I guess a former owner put this tag underneath the grips to be found exactly there. Where else can you hide a piece of paper? And why hiding? Maybe a gag of the old owner.
And Joe states:
"If my math is right, and this piece of paper was inserted upon manufacturing, it's roughly 70 years old, but doesn't look it." He doubt it, too.
Just my 2 cents.
