I took apart several of my instruments and measured them inside out with calipers. I only used the interior measurements for the overall sound tube and designed the exterior details of the instrument to match the interior. I also moved the 3rd valve slide to the right. I guess for making the valves identical. Not exacly sure after several years if they are really identical, do not remember.
