Hi, the Majestic is 1929, and as you know, is built like a tank and they are impressive performers, especially compared to radios just one or two years earlier. The electrodynamic speaker was a major improvement over lesser earlier designs in both volume and tone. They are desirable. Here's the schematic:

The Westinghouse: need a model number.
The Philco: 1946. The postwar radio/phono consoles are not as popular with collectors, but who's to say what you might like? Nice radio. The changer is 78 RPM only. There are people who specialize in restoring changers like that if needed. The mechanisms can be tricky. Here's the schematic:
