Kaweco Sport Nostalgic Octagonal Pen Clip

The Clip is for all pens of these series:
Kaweco CLASSIC Sport, Kaweco ICE Sport, Kaweco SKYLINE Sport, Kaweco AL Sport, Kaweco AL Stonewashed, Kaweco AC Sport, Kaweco BRASS Sport

The original Sport model of 1935, which serves as a template for all of today's sports models, had like today's models also no clip. The clip has only existed since about 1998 as a "slide-on clip" as an extra accessory to it.
