Up for sale here is this set of 4 matching vintage large black Bakelite & metal rectangular pointer knobs. These look like they're from the 1940s or 1950s. They are in great condition with light wear. These have holes through the centers and have some sort of odd shaft hole. I don't know exactly what kind of potentiometer shaft these are for. Please see my pictures for details.

US shipping and handling is $5, and international is $18. If you have any questions, please ask.

I have a number of other knobs, other parts, Magic cards, and vintage electronics listed--feel free to take a look!
