This late-1930s Diamond Point lever-fill fountain pen is commonly referred to by collectors as the “Challenger,” a name associated with Diamond Point pens from this period that closely resemble Parker’s Royal Challenger.
The standout feature is the green marbled body. The material has tremendous depth, with dark green, olive, cream, yellow, and pearlescent tones that shift noticeably under different lighting. It is an especially attractive example of the colorful plastics Diamond Point used during the 1930s.
The pen has been fully serviced and is ready to use. During restoration, I cleaned and polished the body, installed a replacement pressure bar, fitted a new ink sac, serviced the lever mechanism, and tested the pen for proper filling and writing.
The trim shows significant age-related wear. Much of the original plating on the clip, lever, and nib has been lost, and there is visible corrosion and surface wear to the metal components. I cleaned and stabilized these areas rather than aggressively polishing away what remained of the original finish.
The result is a mechanically sound vintage fountain pen that retains plenty of original character. The worn hardware tells its age, while the green marbled body still shows exactly why these Diamond Point pens were so visually appealing in the first place.
Condition
Very good vintage condition with strong color and attractive marbling. The clip, lever, and nib have significant plating loss and visible wear. Fully restored, filling properly, and writing as intended.
Restoration
Cleaned and polished, fitted with a replacement pressure bar and new size 16 ink sac, serviced, and tested for proper filling and writing. See ledger entry for full detail and restoration video.
Known Flaws
The clip and lever have lost most of their original plating and show visible age-related corrosion and surface wear. I cleaned and stabilized these areas but intentionally did not polish aggressively enough to remove every imperfection, as doing so would have risked removing more of the remaining original finish.
