I just don't see the ultimate logic in this argument. So, we're now saying that because an instrument isn't exactly the same bore size as the period instruments (even though it is very similar in all other ways like being cylindrical, valved, bell forward, etc.) that it isn't a legitimate choice for these works? At least more legitimate than something conical? To me, that ignores over 100 years of progress in making brass instruments.bloke wrote:...any more than there is a tuba-bore Jim-Self-o-phone part.J.c.

Do we know why the instruments that were produced back then were the specific dimensions they were? There could be any number of reasons to explain any one of the dimension choices. What we know for sure is that there was a goal by the composer for a specific sound. Does that make modern versions of that same concept invalid because they are produced with different levels of knowledge and technical skill?
The designs of brass instruments have been determined by trial and error since the very beginning of their existence. I see no reason for that to change now. However, just because more knowledge of the process leads us to produce instruments with slightly different dimensions than the original ones doesn't mean that they are no longer the same instrument. Making a modern day cimbasso with a larger bore does not make it an F tuba anymore than it makes it a clarinet. The design concepts of the two instruments are totally different. The essence of the design intent is what matters. Using an instrument that honors that intent is how some of us make the choices of equipment we make.
