This pen showed up in a drawer here.  Nobody knows where it came from or how long it has been there, but it looks like it’s been a very long time…  Still, as an interesting piece of history, I felt it should be shown here.  Given the simplicity of the pen, I decided to only upload a picture of the writing sample.
