Try posting here http://168.103.222.44/cgi-bin/forums/index.cgi especially the radio restoration forum.If you know what tubes it has, that would be of some help in identifying your radio. There is also a value guide that has alot of radios on it. Another thing to do would be to search e-bay.
Do you live near Mariestad? It has been a few years, but I remember that there was an electronics/cellular phone store there that had a large collection of old radios on display in a back room. If it wasn't there, it was off the E-20 highway between there and Gotene, or in that general vicinity.
I remember that there was a Mcdonald's at the exit and it was just past it on the right. I'm pretty sure that it was the exit for Mariestad. I might be wrong, as I wasn't driving. If you find it, they might be able to tell you the value.
