Vintage Truetone Portable Radio, Model D3840, AM Band, 6 Vacuum Tubes.
Truetone was the private label radio, television and electronics
brand of Western Auto Supply Company of Kansas City,
Missouri.
In the late 1920s, radio was taking the country by storm and
Western Auto was looking for new items to add to its line of
merchandise.
After selling radio tubes under its "Wizard" brand in the 1920s,
the company offered its first Truetone brand radios in 1931.
