There are not a lot of mains only valve sets I agree, but in addition to the Ekco A22 which I mentioned earlier (the dial is not made of acetate or celluloid as is often quoted), what about such models as the Bush DAC70 that have dials more commonly seen on portables?
Turning to mains/battery or battery only valve sets, there are many that have perspex dials. Examples from sets that I own - Vidor Vanguard, Ever Ready Sky Emperor/Berec Commander, Philips Colette, etc.
Regarding heat produced from bulbs. Obviously that depends upon the wattage of the bulb and how well designed the set was in the first place as to whether it is an issue or not.
Going back to the two mains only sets I gave as examples - I've never heard of a problem with a heat damaged dial in the Ekco A22, but with the Bush DAC70 it is a very common problem.
