This is a Used Original GM Chrome Dash Radio Knob I acquired in a Former Chevrolet Dealership Parts Stock. This was among Several Dash Knobs Stored in a Parts Room Drawer. Some Had Packages Some Did Not. None of the packages were savable unfortunately.  I Believe this is 1968 Chevrolet Radio but not sure. The Knob Does Have A Pit in the Chrome on the Outer Edge. I have a close up picture of this included.  Used but it is in presentable condition. FREE SHIPPING IN THE US.
