I have doubts re the body being a gen Fender. It looks "multipart", glued and varnished. There is an evident "part" of wood near the jack, you can see a join. also the rear chamfer looks to sharp to me, not rounded enough. Agree re the decal, deffo not original. He says he got the neck from the US due to the old one breaking. Hes in the UK, why get a US neck?
As he has headed his ad as "Fender Jazz", I would avoid, even at a low price. Looks heavy too!!!
