This pocket pencil and point protector were made by A.W. Faber-Castell. The point protector is nickel-plated and has a gold-plated tip and slide ring. Close inspection of the tip reveals a small imprint: “A.W. Faber Paris”
I’m not certain of its exact age, but an example can be found in the 1909 company catalog among several varieties of Taschenstifte:
The pencil I have placed in it is flat (flach):
But its original pencil, though similar in color and length, is oval:
Pocket pencils like these were manufactured at least until the 1930s, perhaps even up to the Second World War (I’m currently looking into when the Eberhard Faber Co. stopped making them in the U.S.).
The touch of gold on this model suggests it may not have been your every-day type of pocket pencil, but I wonder for how many years it was common—and expected—that you’d carry something similar every day.
Thanks to A.W. Faber-Castell for the scan of the 1909 catalog.
