Here is the Nov. 2, 1845 birth and Dec. 9, 1845 Solingen baptism record for Carl Ernst Schmachtenberg, son of Abr. Schmachtenberg and Wilhelmine Meyer. Note that the book "German Knife and Sword Makers 1850-1945" by J. Anthony Carter notes that "swords and sabers were made prior to 1918" and so it is possible that C. E. Schmachtenberg died before or during WWI.
