Up for sale here is this set of 2 new Ohmite round black Bakelite pointer knobs. These have a shiny black finish and look really good. They are 1.25" in diameter at the base.  These have an unusual hole--they are for a 1/4" round shaft with a flattened edge, so not a D shaft exactly.  They will fit a D shaft, but there's a little bit of a gap left so you'd want to put in a little bit of a toothpick as a shim or something to hold it on perfectly.  The hole has a metal sleeve in it, so you could remove the metal sleeve, drill out the hole to 1/4", and I think just press-fit these to a 1/4" round shaft.  These will work fine for a 1/4" shaft with a flattened edge or a D shaft, though.  The white pointer is exactly across from the flat spot—it corresponds to the #11 marked on the bottom.  Please see my pictures for details.
