WTB Sheaffer Snorkel w/open flex nib, fine or extra fine. Nib must be factory marked “FF5” (Flexible Fine), or “FX5” (Flexible Extra Fine). See Pen Hero Gallery, "Sheaffer Snorkel Nib Codes" to see correct marking on open nib. No engraving on cap band, barrel or cap, and no metal caps, so an Admiral, Saratoga or Special. Prefer black, if possible, burgundy is OK. Other than stated preferences, collectible color is not important. Would consider a flexible fine or extra fine Signature with appropriately marked Triumph nib with NO engraving on barrel, cap, or cap ring.
