A marking device includes a plurality of individual marking pin assemblies. Each marking pin assembly is spaced an angular distance from each adjacent marking pin assembly in the marking device to form a generally fan-shaped array. An arcuate object to be marked by the marking device is placed on an object support plate. As the arcuate object is rotated on the object support plate, the plurality of marking pin assemblies in the marking device operate to selectively imprint a plurality of preselected characters in the circumference of the arcuate object.
