A few years back I bought a Dunhill AD2000 Fountain pen, I liked a great deal. I always wanted the ful set, meaning Roller, BallPoint and Pencil if they made it. After a couple of unsuccessful trys I was able to buy the Ball point but it had an empty refill. Can any tell me the correct refill the one in the pen is not correct and interferes with proper use So Please if anyone knows let me know.Thanks Steven
