Here is a very detailed high quality Trumpet.
It was modeled in Blender 3D and later adapted to 3D Max 9.
The rendered preview files were also rendered on Blender 3D. The model uses the Subdivision Surface in Blender, and Turbo Smooth modifier in 3D Max, so it's resolution can be adjusted easily.
The Blender and Max files contain the whole preview scene with all textures included.
I have tested all the files and they all work properly on their respective applications.
Thanks for looking!!
