A beautiful FP: Mabie, Todd & Bard straight-cap eyedropper with a Hand Hammered gold filled overlay, New York, 1900-1907 (according to Schneider, Fischler, I, p.147) I find Mabie Todd overlays to be the most beautiful in the world. Imprinting on the indicia with the 1880's patents. The under-and-over feed is composed by three pieces: a gold overfeed, the HR underfeed and a bulb ending with a long two twisted wire "tail" that can be pulled out with the finger for filling the FP with ink without unscrewing the section (US patent 631.909 from August 29, 1899).
The FP is 133 mm long and 153 mm capped.
