Gary anyone who has a 3D printer can download all kinds of files from places like 'thingyverse', here are just a few of the knob designs available on there. Our club could make them because we have 3D printer, the cost of the filament is next to nothing, time on the printer is sendary to the time to make the design in a CAD type program, and but the cost to mail would make it prohibitive for a single knob. If you can find someone locally who has a printer, it would take minutes to print. It is also possible that one of the designs that are alredy avaiable could be modified. We have made knobs for older radios, and of course you can makes them in whatever color you fancy, but one of the grey filaments seems to be very close to the grey's used by many manufacturers.
