This is something I actually know something about, having collected antique radios for the last thirty years. The collection stands at about 300 sets at this point and it is what led me into my work fixing amps. If you can find an AM-FM table radio with a power supply good. They're not very common though, and you could do well to look at either Packard Bell or Gilfillan-both very well made west coast models. Also if you can get a Farnsworth AM-SW table radio they are among the best consumer radios ever made. If it's a series string set, just recap. What you will mostly see (in the US) is GE, Philco, or Zenith because they were the most common and also the best made, particularly Philco. Zenith was more stylish but not as solid. In Canada you will often see Marconi, Canadian GE, Northern Electric and many others we rarely see here in the states. I think Simpson sold under the trade name Serenader if memory serves me correctly. I don't know much about European or British radio sets except that my grandfather had a Grundig he was very fond of and it had marvelous tone and reception. I have seen Grundig, Telefunken, and Emud sets occasionally but they are not popular with American collectors. The only European radio I'd like to own is either a Bush, or a Volksempfanger-the German "people's radio" of the 1930s and 1940s. What you will also mostly see is AM and short wave, because foreign DX-ing on cold winter nights with a long line antenna up in the attic or out to the barn kept people in touch with the outside world in the thirties and, during the war you could listen to the BBC, Radio Moscow, and the Deutsche Rundfunk for levity and fantasy of a high order. Everyone in 1941 knew the Germans were going to lose the war eventually except the Germans themselves. The Volksempfanger was specifically built so as to not be well suited to receiving foreign broadcasts-information control was then as now governmental interest. If you were a German during those years and you were caught listening to the BBC, a jail cell or a bunk in a konzentrationslager awaited you as a subversive element. It is interesting in this context to read what Josef Goebbels had to say about truth being the enemy of the state. You can still have a lot of fun with those radios listening to foreign short wave news services although the internet is fast making that a thing of the past. The FM (frequency modulation) system was invented by Major Armstrong and resisted by RCA. Armstrong set up what he called the Yankee Broadcasting Network on 42-50 mhz and there were a number of BC stations on that band, Between Sarnoff and the FCC, they conspired to give that frequency band for television, thus putting Armstrong out of business or so they thought. The new FM broadcast band is what we now have, 88-108(?) mhz. You can find some Zenith radios from 1946 which have, in addition to AM, both the 42-50 mhz band and the 88-108 mhz band but they are rare and valuable to collectors. Incidentally after Sarnoff massively infringed Armstrong's patents and sold licenses, Armstrong committed suicide after assaulting his wife. She continued the litigation and won every damned lawsuit against RCA and its licensees. She used the money to restore the Hispano Suiza car that ARmstrong first courted her in in the 1920s when she had been David Sarnoff's secretary. You can read all about this in Tom Lewis' excellent book Empire of the Air, the documentary of the same name, and nuerous other interesting books such as Armstrong's biography and Gerald F.J. Tyne's Saga of the Vacuum Tube, as well as Hugh J.G. Aitken's "Syntony and Spark. I've never much dabbled with car radios except to curse the Sylvania engineers who developed Loktal tubes.
