New Old Stock pens are always fun, especially when they are 70 years old. We just discovered this Esterbrook M2 complete with its cap sticker and box. There is a little shop wear on the pen but nothing bad. No cracks in the cap. It comes with a still-working aerometric filler! We think someone might have used it once, as a little ink came out when we filled it with water. Its steel 1551 nib writes a nice fine line. 13.5cm capped.
