estate car boot cover (Yatton Keynell SN14)

can anyone use this estate car boot cover? Unfortunately, I don't know what car it fits. It's got protruding oblong sections on each end which would fit into the same shape holes on the car itself. It's 1246mm long (not including the protruding oblong sections). "Unten" means "under" in German so it's maybe from a German car? Even if you don't want it, if you know what car it fits, please let me know. Thanks
