Circa 1720, with fine decoration of the pieces and intricate embossing and decoration of the leather case. Complete with all original compasses, rules, attachments and nice bone inkwells. There is some wear to the corners of the case.All compasses are stamped with the initials IR and two keys. I do not know the significance of the stamp but assume it is the maker’s mark, probably from Augsburg or Nuremberg as these cities were the center of German instrument production in the period. A museum-quality piece with fine instruments and completeness.
