Hong Kong & Asian sets generally are often sold by many companies. "Badge Engineering". In 2012 many well known brands of UK set-box for TV are actually made by Turkish Vestel. Many brands of TV in UK and Ireland were actually Turkish Beko.

 

Here a Binatone that is obiviously the same chassis as the Academy Compass

Binatone Worldstar MW/MB/LW/FM/VHF

Similar Models were sold as Oscar and "Silver Space".

There is of course a "styling" nod at the last expensive Zenith World Radio, the uncompetitve 7000 series. (Sony & Grundig had Digital displays and other features).

These are not of course great performance radio sets, but slightly better than the MW only Hong Kong transistor set and benefiting from the larger cabinet, ferrite rod and loudspeaker.

An Ebay seller claims the Binatone Worldstar is 1975. It has the exact same bands and controls.

 

A feature not mentioned in the "notes" is that the Tuning cursor has an LED with brightness controlled by signal level as tuning indicator.
