These matters are typically trade secrets in the saxophone world. It's not the brass family, where players and even manufacturers often speak of certain bore dimensions.
Doing that when talking about a conical-tube instrument like a sax - or even a polycylindrical tube like the modern clarinet - would probably mean revealing all kinds of design and engineering details, stuff even the marketing department has no business dealing with.
And finally of course, once a model is out of production and the mandrel and toolings retired, it is essentially nobody's business. The knowledge is the manufacturer's to destroy.
