Antique radio value guide (on the example of the Swedish and Norwegian radios)
The most rare radios are the ones that only one collector has and as no one else even saw anywhere else. In consequence, so should be the most common ones that almost all collectors have and which, in addition, it can be seen in markets and auctions everyday. So far it sounds simple. If now a collector claims he has a very rare Philips model, like he has not heard that any other Swedish radio collector has, is it then necessarily so rare? Perhaps it is rare in Sweden because it not included in the Swedish model program.
For example, it can touch about a Norwegian-built Philips device, which someone brought here at one move. Then it can be rare in Sweden, but common in Norway. Similarly, a radio that sold poorly in Sweden could still have been included in a large production series, most of which were exported. It is not so easy to always judge on the basis of the national or even local access how ordinary or unusual a radio is actually. A radio collector from Gothenburg may think that Uddenbergs or Särnmark's radios are fairly common, while one in Malmö looks Bergh & Co. models often used. A collector from Stockholm or Luleå would definitely not agree with any of the earlier ones. So what can you be sure of and what should you go for in an assessment? Sometimes it can be good to generalize, to create structure, despite the risk that land in prejudices and preconceptions.
In the radio dealers own pricing lists from the 50's, most radio are available apparatus sold in Sweden between 1930 - 54 listed. Here you can besides data on manufacturing year also find out what a particular radio cost new. If you have an obvious Swedish-built radio, which is not in the list, though which must still be manufactured within the time frames of the list, then it is included security quite unusual. Examples of Swedish brands that do not exist in the list are: Bring, Miko and the Cooperative Association. The latter are, however, not always with Swedish made.
Lastly and finally, it must nevertheless be most important to ask the question what remains today. Generally low quality appliances can after all, they have been thrown away to a greater extent than the more solid ones. Certain models may have contained parts that made them more suitable "slaughter" objects for the builder than others, etc. The only straight is really just to wander around at auctions, flea markets and fairs and watch yellow magazine, internet ads and so on. The larger the substrate you can building their observations on the safer they will of course. To have contact with other collectors and compare each one's own experiences further increase knowledge. Internet is an excellent one aids and forums in this context.
