Earlier today, I posted regarding a pen I had that had a threaded barrel jewel. Well, here's an example of one of my pens that has no bottom jewel. I am assuming that it came from the factory this way, as it still has the original price band on it and it does not look like the jewel was broken off.



These are the same pen, just different backgrounds.
I figure that since it was missing the jewel, no one bought it. That's why I found it as NOS! There's always something unique out there.
