Waterman made a ton of pens in the 1940s that all looked very similar but gave them a ton of different names. We think this is the Waterman Stalwart, but you are welcome to correct us, if we are wrong. Blue flames shoot through its beautiful celluloid cap and barrel. No cracks mar this beauty, but you can see a deep scar made by the pocket clip to the right of the bottom of the clip. There are other signs of wear, and the section has lost all of its luster. We restored this vintage pen with a new ink sac. Its 14k gold nib writes a nice fine, maybe fine-medium line with a little bounce. Not a true flex of any kind, you can get a touch of line variation from it. 12.2cm capped.
