Thank you all very much for identifying the mark and manufacturer - now there is a topic for study. The mark may well correspond to the period of the imperial eagle, although there are also questions about the eagle. I’ll add a few photos - the lighter zone of the eagle, the crooked letters of the monogram and the asymmetrical swastika are incomprehensible.
