Just needed an "ink pen," as they used to call 'em on the Sho', despite the fact that in that part of the country "pen" and "pin" are already pronounced differently, so the qualifier's not really necessary. Reached into desk & pulled one out; it is from Dillons, which means it came from Kansas. I also have a pen here from the U. of Md. Hospital in Balto, and a mechanical pencil I'm pretty sure I bought in Chestertown in the early '80's.
A more complete trail could be reconstructed from the evidence of writing utensils in my home.
(If Dillons were on the Sho', it'd be called "Dillons's.")
