Heard it on the radio

I just found this old Philips radio, aparently it´s correct for a split.
What I have found out so far is that this radio was introduced in 1951 and is called Philips Autosuper 491. and the picture of it mounted in a split is from the book Besser fahren mit Volkswagen.
I just tried to hook it up and it buzzes but no music so far, maybe I should find a antenna and put in.
I will consider selling the radio as I already have a radio in the oval, so drop me a email if you are interested.
