This may be one of Columbia Phonograph Company's products since the model number follows their numbering scheme. It may have been one of their export models. I don't see this one listed in Riders or Beitman references. You might want to check Gilfillan Brothers models 34, 55A, 55B and 5X which have the same tube line-up. Schematics for those models can be found under the "Resources" tab of this website. Hope this helps.

Dear Steve,

I verified, and indeed,according to your answer, the radio device is made under the schematic 55A of Gilfillan Brothers. My question is : Why the radio device has the brand Columbia C150 (but this doesn't mather anymore).
If you like, I can send you photos afer I will restore the radio device.
Thank you,
Ion

Ion: we would love to see your restored radio. I'm not sure about your model, but many radios were branded under various names, or produced under license agreements. Your Columbia model doesn't seem to appear in US schematic listings since it was probably an export only model. Good luck with your project, and happy soldering!
