The Blaupunkt has an individual setting for each button, in other words you can switch between radio stations by pressing a button, which was quite revolutionary for its time. It also has an external (foot operated?) button, which I am not sure the what the purpose is for.
I am not sure if the radio is still working, as I haven't tested it myself, but it seems to be in a good, complete condition. These radios are highly sought after by collectors in Europe and the US, and spares are available.
