No and no. The details on the Zunow BB were part of the mold that was used to cast the shell. Traditional pantographing used a scribing device (or end mill bit driven by a small motor, like a Dremel tool) attached to an articulated scissors-like arm. A small probe riding in a guide stencil would move the arm in the desired pattern and one could get various degrees of enlargement or reduction by altering the pivot points on the arms. I believe the first use of this tool was by artists (with a pencil or other drawing implement in place of the end mill bit of course) to copy drawings repetitively in the days before cameras and copy machines.
Nowadays of course, the arms and guide pin of the device are gone, all that remains is the end mill bit which is driven by a computer-controlled machine.
Two characteristics that can usually be used to distinguish a pantographed de sign from a cast or stamped design: Pantographing often leaves a very sharp and crisp edge around the perimeter of the design. Also, the bit often leaves swirl marks at the base of the cut, though this is often obscured by paint fill. Stamped and cast designs often have a softer look that appears much more a part of the object... it tends to look like it belongs there while pantographing more oten looks like an add-on (IMO).
