This is a very nice re-conditioned 1930's Magic Chef burner control knob. These knob/dials use a set screw that screws into the brass burner valve stem. It is in excellent condition, no chips or cracks - set screw included. Please view photo prior to making your purchase - we have a very limited supply of these knobs. Call with any questions.  

Also available are the MC brass burner control valves.
