According to the attached photo, I found in the Mercado Libre in Argentina a radio with the same dial as the radio I am trying to identify.
Also in New Zealand according to the attached url, I found a radio with this dial frame.

With these new references, it may be possible to identify my radio, because by the electronic valves it would be an American project, but it is being found in Brazil, Argentina and New Zealand.
