vintage chrome metal knob for manual stick shift, retro automotive rat rod gear collectors car

Very heavy metal knob for a stick shift, very shiny chrome with no makers marks or auto emblem. I don't know what this came off of originally, or if it was OEM or a custom add on to begin with.

It's clearly been used, the chrome doesn't have a lot of scratching but it does have a little spotting or pitting - it's not new, or flawless. This fits a 1/2" standard thread, see photos.
