This is a BIW Custom Bb trumpet in raw brass! It has a Bach 72G bell with a #7 leadpipe and a CarolBrass body. It was custom-made to play similarly as a Martin Committee. Comes with a case and a choice in tuning slides.
 
From Bach's website:
"[The #7 leadpipe has a] darker tone, more free-blowing than 25. Dark, similar to the 43, but not nearly as bright. ... [The 72G bell offers a] strong, powerful sound, darker tone than 37. Nice projection, probably the fullest sounding bell Bach makes. High range sparkles."
