Greetings O Estie Experts...I have here an older model dollar pen, black, with a single-hole clip (V-clip?) that I bought from Hobiwan on the Bay several years ago. I just recently started using it regularly, took a good look at the imprint and found it, well different. The word "Esterbrook" (in the usual script runs length wise down the barrel, but "Made in USA" runs around the barrel. What really struck me though, was the fact that it read just "Esterbrook", and not as one would expect on a pen of that vintage, " R.Esterbrook & Co." I have one other V-clip pen on which the imprint is normal, with the name, and "Made in USA" running lengthwise.
