and distinction on these points - those drawings were already H-B (Halter-Barnes) so have the DNA of both men, which subsequently was taken over by Vianney Halter, solo. So insofar as these examples, I have no issues and completely understand your point.
But if one were to look further back, and consider that the original concept drawings for the Classique; Trio; Antigua; MAY have originated with Jeff Barnes, solo, and he then went searching for someone to make them complete watches, then, to my mind, the entire discussion takes on a different light and to me, have the DNA of ONLY Jeff Barnes (at least in terms of the design, which is the aspect you limited this discussion to)
Anyway, I appreciate the discussion, and thanks for digging up those old pics. Nice to see them again after nearly a decade!
