This is a Bakelite vacuum tube radio. It was used as a decorative item, so I only wiped the exterior and did not touch the interior. It is the type that is powered from a light bulb socket. The plug is also elaborate Bakelite, so it appears to be original. I purchased it as a first-time offering from a prestigious family's collection. Size: Height: Approximately 18 cm Width: Approximately 21 cm The following information was borrowed from the website of the Japan Radio Museum in Matsumoto, Nagano Prefecture. National R-11 Model 3-tube regenerative receiver Matsushita Wireless Around 1936 26 yen TUBES: 24B 47B 12B, Magnetic Speaker A very small radio using a thermosetting plastic cabinet that Matsushita called "Mats-Light." It was an ambitious product that domesticized the plastic radio, which was popular in the United States under the brand name "Bakelite." In the United States, transformerless radios were already widespread, so even at this size, it was possible to incorporate a high-frequency amplifier with four tubes, but in Japan, where large transformers were required, a 3-tube type was the limit. Naturally, it became heavy, so it was easily damaged, and few remain in good condition. Although it should have been superior in mass production, the price did not drop dramatically as it did in the United States with mass production, and it was more expensive than similar models with wooden cabinets. For this reason, the early plastic cabinets quickly disappeared from the market.
