This RL Drake NEW Pointer Knob, is Used on Many Drake Radios and accessories like the W-4 Wattmeter and RV-4C VFO. ( also offer full sets of these knobs for the C-Line and B-Line and TR-4C in my other listings!)I am very pleased to offer this new Grade A Plenco Phenolic, original knob for a great low price!This knob is what you will need to replace all the pointer knobs on your T-4XC/R-4C, T-4XB/R-4B, R-4/T-4X and TR-4C radio Sets. (They are the Same knobs used on many RL Drake radios) You will be very surprised when you see what a difference it will make to replace the old pointer knobs that have lost their shine and have yellowed lines rather than nice bright white lines they had when new.I also have full sets of them for individual Receivers and transmitters. You can save money (and shipping costs) by purchasing full sets and then all the knobs will have a beautiful shine and brigh white factory painted lines!
