Reference / Edition: “51” Custom Aerometric (black barrel), fluted gold-filled cap with a feather-like ribbed crown.
Length: 13.9 cm.
Diameter: 1.16 cm.
Nib: F.
Period: 1950s–1960s (Aerometric version, produced approx. 1948–1969).
Materials: Black resin/Lucite barrel and nib hood; outer cap in gold-plated metal (gold filled), with vertical fluting and a feather-like ribbed crown; arrow clip without Blue Diamond; silver-tone metal retaining ring between the hood and the barrel; hooded nib with visible tip; Aerometric filling system (smooth barrel, without a rear blind cap).
Condition: Good overall condition for its age. The black barrel retains an intense, even shine, with no dents, cracks, or material loss; the rear end is intact, with only superficial micro-scratches visible in reflected light. The cap’s gold plating remains bright across the surface, with fine signs of use on the fluting, a few dark spots near the clip, and plating wear along the lower edge and rim of the crown. The clip is firm and the nib tip is straight, with no deformation. The photos do not show whether the filling system works.
Accessories: Loose item only; no box or papers are visible in the photos.
