SAVE OODLES! PLEASE READ FULL DESCRIPTION. Original Vintage O'Keefe & Merritt Burner Control Knob. Often we get knobs that can be good looking and function perfectly yet in need of a bit of repair that in no way will effect the front of knob appearance. This is one of those knobs. The rear 'D' was chipped, we have repaired it - the front view will look every bit as gorgeous as your other burner control knobs. We always offer considerable discounts on these knobs. Other then this, it is a great working knob. Please view all photos prior to making your purchase.
