Well the 35Z3 doesn't have a tap on the tube heater for a pilot light, so in this set they have the dial lamp paralleled with a 40 ohm power resistor, between the hot side of the power line and the plate of the 35Z3. In some sets, like my 42-327, they used a 120 volt candelabra bulb across the power line to light the dial, and basically the whole back of the set for that matter.
As for the cabinet trim it's probably medium walnut or dark walnut shading lacquer that was used, Mohawk paint makes both of these in dye and pigment based varieties. If it really was black then lacquer or acrylic paint will work, as you can coat over either with clear lacquer.
