Hi all, i am a newbie here. =) I have recently bought a Sheaffer 444 from Ebay and i was quite curious about its details. I went through some research and found out that it was not from the 1990s but i was unsure whether it is from which era or Sheaffer 444. The "labeling sticker" states SHEAFFER 444-X-F. Can anyone please help me identify this beautiful pen, thank you =D
