Up for sale here is this vintage dark brown (I swear it's very dark brown and not black) octagonal Bakelite knob, probably from the 1930s or 1940s and Made in USA.  This is an old radio knob, but it came from an estate so I don't know what it goes to.  Very nice shape, nice and shiny, includes the set screw.  Please see my pictures for details.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.
