A set of four knobs reliced from the factory for adding a vintage look, or maintaining it on an already aged instrument. These have embossed yellowed numbering for an authentic aged look.
These are imperial sized for installation on knob shafts of 6.35mm diameter (as opposed to import at 6mm). These knobs don't have as much wear on the top as the picture makes it seem - the lighting makes it far more visible.
Diameter bottom: 26mm
Diameter top: 24mm
