It is Dixon's Ticonderoga pencil, which was released in 1913 and is still in production.
When the Ticonderoga pencil was released,
the model name was different for each hardness.
The model name means hardness.
No.1 (Very Soft) = 1385
No.2 (Soft) = 1386
No.2 5/10 (Firm) = 1387
No.3 (Medium) = 1388
No.4 (Hard) = 1389
After that, the model name was changed to "Ticonderoga 1386"
and then to "Ticonderoga 1388" after World War II.
