BACKGROUND:
This knob was pulled from some old radiogram equipment, remember them? They were often quite large pieces of electronic furniture, the centre of a family home's entertainment with a tuner, record player and some of the fancier models also had a reel to reel tape recorder built in.

This type of knob design was often found on these units but I have also seen them used on small standalone audio amplifiers.
