Unless you had the sac replaced, probably the original. The Pli-glas (PVC) sacs are almost indestructible. Not as big a fan of the aerometric fillers. It's why my 51 is a Vacumatic. Easier for me to fill, holds more ink. Potentially more maintenance, but...😉 Great workhorse pens, the 51s. And a design that most other brands copied at one point.
