Despite the star of david, Henschel und Sohn AG (see the HuS letters inside the star) are not a jewish manufacturer.

Well, the use of the six cornered star is not unusual in Hessen (I am living in south of Hessen, Kassel is in the north of Hessen).
E.g. both beer breweries are using this kind of star - and they are definitely not Jewish.
