Reporting question for Potentiometer - CTS, Audio, Knurled Shaft, 3/8" Bushing

Product:
Potentiometer - CTS, Audio, Knurled Shaft, 3/8" Bushing

Question:
Why don't these pots say CTS or their value (250K, 500K) on them? They're the only CTS pots I've ever purchased that don't have this info on the casing.

Answer:
It appears as if CTS has reformatted the part numbers recently, but the reasoning behind this is something we aren't able to comment on.
