    You may find two different manufacturers for this model and a few others before 1957: The production began before the move from Shanghai to Hankou in 1957 but production continued in the Hankou Radio Factory 汉口无线电厂. The story is: Shanghai Radio Factory 上海无线电厂 was etablished in 1953 but moved 1957 to Hankou (Wuhan City, Hubei Province) and changed the name to Hankou Radio Factory 汉口无线电厂. But you can also read it as Hubeisheng Hankou Radio Factory; Hankou 湖北省汉口无线电厂 or Hubei Hankou Radio Factory: Hankou 湖北省汉口无线电厂. Normally it is then in trad. Chinese characters.
