Hello all - This is my first time in any forum, so please forgive me if I do something incorrectly. I am wondering if anyone knows of a pen repair shop that might be able to fix my very favourite Grifos fountain pen. It is a celluloid and sterling pen, with the sterling being the broken portion. I unscrewed it to check the ink supply in the converter, and when I put it back together something popped and the parts would no longer screw together. I spoke with a couple of different repair places and they all said that they wouldn't be able to get parts for the pen. I am trying to avoid having to send it back to Italy for repairs, as I could probably purchase a new pen more inexpensively. But this is my favourite. Any help would be appreciated.
