Yes, that's a funny one.
It looks like a Dirigent which, I believe, it basically is but it reads Grand Prix on the dial.
It is the radio part from a Grand Prix TV 609K Radio/TV combination where the TV part
was cut away and the speakers (strangely) mounted underneath.
The plastic backside has obviously been cut from the larger cabinet to fit this slim one and
the chassis will live a warm life in there.
A nice piece but not original like this.
It's not unusual to see radio chassis' "rescued" from dead TV sets like this.
I believe that Frede (Classic) has a similar set only in a different and smaller cabinet.
It looked like this originally:
and from the 1963 catalogue:
