Nib: XF 14k Gold
Sterling Cicelé hit the market in 1964 (the pen was finished in 1963, though, Parker's 75:th anniversary)
The conformed grip allowed the user to adjust the nib to his hand "...like one adjusts the lens of a fine camera...",
The first Parker 75 was offered with a flat clip-screw, often referred to by collectors as the "flat-top" 75. In 1970 the clip screw was re-designed leaving a small hole in the clip-screw, this way Parker could offer to add an emblem or company logo to the top of the pen.
