1910s Waterman's 12SF, black chased hard rubber, slip cap, with gold filled barrel band. Great color, great sleeve filler, good imprint and chasing. So what's wrong? The cap is from a regular 12. It's been there a while and the chasing matches perfectly, but it is a replacement. The nib is the small curved New York, #2. Like many early W'man's it is not all that flexible. A cool pen.
