Very early Swan 3612, eyedropper made of ebonite, chased (very cool pattern, combining stripes and waves – and well preserved!). Fantastic, soft wet noodle nib with a flex up to 2.1mm easily (goes further, but I don’t want to overflex). Over-under feed. The is a certain wear on the upper band, please check the photos. Slim pen, 13cm closed, 16cm posted. The pen has been cleaned, conservatively polished and protected from oxidation.
