I've recently acquired this sheaffer. I'm not an expert by any means, so there probably are several errors in my description of the pen as a Sheaffer Balance Statesman. It has a lifetime nib, a 1000 price code and, most puzzling to me, a tuckaway clip. The cap seems to belong to the pen, as it screws down securely and has the same plastic as the pen. Am I mistaken in believing that the clip is an oddity?
