This is an Aurora Hastil Sterling Silver Fountain Pen c. 1980. Designed by Marco Zanuso in 1969, the original slender, cylindrical stainless steel Hastil with 14 karat white gold nib is in the permanent collection of The Museum of Modern Art in New York City. The Hastil has a patented leak preventing capillary feed called Idrograph. The barrel end has pair of black "brakes" to hold the cap securely. The nib section is ribbed for secure grip and has a serial number stamping. The pen was successful and was eventually made in precious metal and laquer finishes. This 5 3/8 inch long sterling silver cartridge / converter model has deeply cut engraved lines in the cap and barrel, a chrome plated spring loaded clip, and a 14 karat white gold medium nib. The cap and barrel ends have black disc inserts and the cap top one has the Aurora name on it. The cap and barrel have sterling silver hallmarks near the end caps. The success of the Hastil inspired other slim cylindrical pens in the 1970s such as the Montblanc Noblesse and Slim Line models.
