I have filled this pen up with some old original Parker Quink that I had for donkeys ages. It writes really smoothly.
The ink I put in is blue but the pen is writing in black at the moment. I think it will take a while for the blue to come through. I have used the pen for a couple of days and find I need to shake it to get it started. After that it writes well until you put it away again.
There is no guarantee on this pen but it seems in good vintage condition to me. Please look at the pictures carefully as they form part of the description.
