Item: BLACKBIRD fountain pen (Mabie Todd & Co. Ltd.) Self-Filling Pen, black ebonite finely line-engraved with brown-bronze patina, cap without a clip, side-lever fill and 14-carat gold Swan No. 2 nib.
Length: 13.6 cm.
Diameter: 1.1 cm.
Nib: M.
Period: 1920s–1930s.
Materials: Body and cap of ebonite (hardened rubber) finely line-engraved, metal side lever, 14-carat gold nib stamped "SWAN 2 · Mabie Todd & Co. Ltd · Made in England" and ebonite feed engraved "BLACKBIRD".
Condition: Good condition for its age. The line engraving remains sharp across nearly the entire surface, with loss of luster and color shift toward brown-bronze tones typical of antique ebonite, more pronounced in the middle of the cap; the body maintains shine. Light signs of use and wear to the lever plating are visible. The body inscriptions (bird, "BLACKBIRD SELF-FILLING PEN", "MABIE TODD & CO., LTD.", "MADE IN ENGLAND") and the "MED" mark on the end cap are clearly legible. The nib is aligned and undamaged, with small stains of old ink. The filling sac’s seal has not been tested for leakage.
