General Electric Musaphonic AM Radio model 871. I believe it's from the 1940s or early 50s. Although there are no date markings, there are Civil Defense frequency markers on the dial.
Scene file as shown is included with model. Dial lights up via a point light inside the model and translucency setting on dial's surface. Dial also spins. Very detailed and realistic. Modeled from actual radio using digital photos and scans. Includes desktop model as well.
Uses ray tracing to achieve the look shown. There are many transparent parts and lots of hi res image maps. Background uses Lightwave's texture environment.
