My mirror in my 48-2500 was in very poor condition, so having it resurfaced made all the difference. However, dummy that I can be, I attempted to clean the curved mirror in the lid. Disaster! The top coat on that mirror is a multi-coat lacquer coat filled with micro-spheres which act to provide optical gain.
But I have restored several RCA projection sets from the late 1940s, and if you want to achieve optimum optical resolution, resilvering the spherical mirror and replacing the flat front surface mirror is the way to go. These sets can provide quite acceptable bright (though very directional) images when operating at peak performance. Of course, of "close is good enough", then the mirrors you have may be tood enough.
