Hi FPN'ers, I wondered if any of you may know if a converter exists that will work with a Burberrys fountain pen? The pen is approximately 20 years old and came with 2 Pentel FK15N ink cartridges but no converter. I know I can refill the cartridges with a needle but was hoping for a converter that works. Any help from someone that has already gone through this would be appreciated. Thank you, -Rob
