Peffenhauser, or Pepfenhauser, appears in the records of the Stadtarchiv Augsburg as a casemaker as well as a watchmaker. The case may, therefore, have been made at least in part by the clockmaker, perhaps incorporating an earlier cameo.
Watchmaker: Wilhelm Peffenhauser (German, Augsburg, born 1618, master 1647, died before 1683)
