Bryan Cather asked if there was a source for knobs for his G.E radio
restoration project.  A couple of places to start the search are:

  Jasper's Antique Radio Museum
  2022 Cherokee Street
  St. Louis, MO 63118
  314 421-8313

  Antique Radio Classified
  P.O. Box 2
  Carlisle, MA 01741

Several years ago when we were at the St. Louis AMICA convention Jasper
mentioned a place in Arizona (I believe) that sells old radio parts.
I've since lost the name of the place, but he will know it.
