Hello Forgive my question re a ballpoint pen rather than a FP! I have 2 Waterman Panta 4-colour ballpoint pens, and 1 Jif (all from France, 1960s). One of them is gold plated, the other 2 chrome. The ink is dried out. I have spare refills, also dried out. Is there any way these can be "revived" ? I presume Waterman don't sell these refills any more, so are there any other brands that would fit ? Are these pens collector items? I'd be quite prepared to sell them. There are only so many pens I can use or even just look at in one day! thank you very much cheers!
