Swiss silver marks

Usually I find this silver mark’s on the cover of swiss pocket watche’s.I would ask additional information about the manufacturer - (K&M) (Bird) (Moon)???
Thx for any additional information.
Best regards

The moon & crown is a German silver mark struck on 800 silver aftre 1888. The bird is Swiss silver mark for the same gradeused between 1882 & 1934. This would suggest a Swiss export to Germany.

Thx “paulh” for your help and opinion.
