This 1953 Waterman Duo 7 Glass-Cartridge-filler is a black model with Gold-filled cap in alternating pinstripe and plain panels. What is particularly interesting about this nib is it writes on both sides of the nib: medium/broad (normal), fine (upside-down)! Great for those who use their nibs for reverse writing. 18K “Keyhole” vent.
New-old-stock and mint with original chalk mark on barrel, showing the price at 7900 Francs. (2) glass cartridge included, one clean the other with ink residue. Can be filled with a syringe (I can include for $5.00).
