:OK, I got that link to your photos to work. I do see the labels that refer to Gt. Britain, although the cabinet and tuning dial styling suggests post-war German to me. There is a UK-based antique radio forum which might be of help. I don't have its URL handy, but you should be able to Google for it - unless somebody here can post it.

In 2006 someone gave me "Vintage-Radio.net" as a British website to post a question. They gave me some helpful information about an unusual Vidor radio. You might also try Frank Goddard via "nostalgicradio@fsmail.net".
