Two modern crescent-fill pens: The Conklin Mark Twain Crescent and the Stipula Saturno. The Conklin is a dome-top with a black chased celluloid (?) body and sterling silver trim. The Stipula is a flat-top with a green woodgrain ebonite body and sterling silver trim.
The Conklin is twice as heavy as the Stipula, particularly the cap. Possibly, this is because its clip and cap band are much thicker.Conklin's ring is set tighter than Stipula's, but neither presents a problem.
The crescent is considered to be an outdated filling system that is used in modern pens only for nostalgic or kitsch appeal. I disagree, and find it to be a very low-hassle, easy to use filling method that has the additional benefit of keeping the pen from rolling of the desk when uncapped (or if the pen is a clipless model). I also find the crescent quite beautiful, particularly when it is sterling silver. If only more of these were available!
