It is always difficult to tell if a Esterbrook Transition is original or a repairman's special. Whatever our vintage pen is, it has nice matching colors. Click the headline for a close-up. We restore this pen with a new ink sac. You might want to pay special attention to the cap. It has a black-plastic jewel with 3 stripes, instead of the usual circles. Also, there is not "Esterbrook" on the pocket clip. No cracks. Tight clip. Light wear from use. You will write a broad line with a little feedback with its steel 2556 nib. 12.4cm capped.
