-Through the early to mid 1900s the engraving was usually done with a variation of a "turning engine" that came to be known as the rose engine. One is pictured here. The acorn-looking white thing to the right is the piece being worked on. The machine is essentially a slow-turning lathe where the brass camwheels in the middle area push the chuck that holds the workpiece off center in a repetitive and reproducible manner. And then there is a ton of stuff for indexing and depth control and who knows what else.
