the early 1930's up to the late 1950's engravings on Zippo
lighters were done by using a pantograph. A finger connected to
the pantograph followed the template contours and the tool at the
top of the pantograph engraved the lighter. It was possible to
engrave the same pattern at different scales. Pantograph plates
have a size of 4 x 4 inches and are made of solid brass.
