I'd guess the exact bore dimensions have changed a bit over time, based especially on the comments here of a retired tech who's measured some of their instruments. But right now, based on what they told me last May, the upper joint starts a lot wider and ends up narrower, and they're tapered rather than poly-cylindrical. I've played Prestige RCs and Prestige Elites, the latter now defunct, and found the S & Ss freer blowing and with more dynamic range. But I wouldn't take issue with your characterization of the sound, and don't know enough about their origin to question your comment on that, either. I've heard here, and the fellow who was helping me at the workshop also said, that Jochen worked with Uebel designing the bore for their Superior, which is not really an R13 knock off, so it seems likely that the R13 would have been more of a starting point for their French bore than a design goal.
