Bach Professional Bb Model LR18037 Stradivarius Reverse Tuning Bb Trumpet "Stradivarius" - .459" Medium-large bore, lightweight body, standard weight yellow brass one-piece hand-hammered #37 bell, reverse construction #25LR mouthpipe, monel pistons, clear lacquer finish. Was used in a professional setting, and has been well handled since purchase. There is lacquer wear on various parts of the instrument, but does not affect playability or functionability in the slightest. Comes with very sturdy bach pro case. Can include mouthpiece if necessary, but can't imagine anyone would want a used mouthpiece. I am looking to sell this instrument as quickly as possible, as I am leaving for a trip in 3 days. Serious inquiries only.
