original closed box. By the description it should contain 6mm BOSQUETTE Type rimfires. Means with a brass base and inserted copper case. Headstamp not known, but most probably the oak-mark of RWS.
What is wondering me, that on the side Label is written: Grosses Kaliber (Big /largecaliber)…what that should mean, as the caliber is only 6mm
here the pics
