Dave, that is my signature under the clip, I determine how the pen will be put together, then Laser Engrave Signature, back fill with some colour and thenput pen together.
As for placement, I found customers not keen on signature on the side---unless my name is Leonardo Da Vinci!. So I put it under the clip, another place that is good is on the top finial, or on the Metal Clip, certain factors involved if it is the top finial, need a flat area, On the clip need a Metal engraver of some kind.
