I'd ask the seller and see if the electronics have been changed in anyway- the standard for the Europa is vol, pan, filter with a Q switch and two 3 position switches for bass/treble. I'd get clarification from the seller asking if those quick change switches have really been changed to something else.
It could be that the seller is just hearing the effect of the cut/normal/boost and assuming it's single coil, series and parallel, but it's worth confirming that the electronics haven't been mucked with.
