The rim and the centre boss cover on this knob is made from brass, if you can remove them they are easy to polish with brasso wadding. Once cleaned to shiny brass and all residue of the polish has ben removed, the brass parts can be sprayed with clear lacquer to help stop further tarnishing.
The speaker grill is painted plastic and it tends to rub off over time. The grill can be removed by careful releasing all the melted lugs which go through the case to "weld" it in position. Then it can be sprayed gold. The handle fittings on the early radios are also brass and can also be removed for polishing.
