I have a Sonora radio (from France I think, circa 1952) with a dial calibrated with city names. 3 bands "O.C.", "G.O." and "P.O." As per the "Plan de Copenhague", which I would guess was an European frequency allocation agreement amoung all the European countries' FCCs. Go to http://www.geocities.com/wa2ise/radios/forgnr.htm to see the entire Sonora radio this dial is from and also a similar radio from Australia. They must never have changed station callsigns in Australia when that radio was made. Like the Packard Bell sets that were "stationized" for the west coast of the USA.

nice radio i like it.heres the same idea but on an old communications receiver a hallicrafters sx 62.these receivers were huge and had a push pull output stage using a pr of 6v6's.it was a true high fidelity shortwave reciever that even had the fm band on it.i sure wish i would have kept mine.

and now the rest...

I wonder where the Sonora company was based? They made plenty of radios in the states, & I think phonographs back in the crank days. I had heard of other foreign models besides this one.
