Oh, I have one of these, but my ink jar is missing. That's my guess for the jar anyway, it is situated next to the pen cubby in the "desk" drawer so I'm thinking that's where you dipped your pen in to write. Er, that would be an old way of writing though. I forget the year on this machine? I know we were using reservoir fountain pens when I was a young girl still...and I'm 60 this year....oh, was that my outside voice? :)
