Hi there, I'm afraid that "Chambure's" vihuela has gained as well "universal acceptance", at least within vihuela experts' circle. On the other hand Jacquemart-Andre's vihuela was, as Eugene suggests, built for different purposes than playing music on it(probably a sort of an exam for someone willing to become an official "violero"). saludos, Ariel.
