"How come you've got so many weapons?" I do like her voice. Soft enough to be ASMR (Google ASMR + Youtube).
At 1:35 she handles his German-made (in Ulm) Walther P99 AS. Variations of these were issued to about 60,000 German police, and to other countries' LEOs.
A Mauser at 10:07 is also presented. No provenance is given for This rifle.
The girl hears that it was used in WW2, but she has probably never seen a Mauser, or possibly she is a "poker player", keeping quiet.
The non-German guns somehow don't seem as interesting in this situation, therefore...
