Key of F/Bb double .468" bore 12-1/4" large-throated, hand-hammered, red brass bell .310 venturi of nickel silver Tapered, hand-lapped brass rotors Solid brass branches and bows with nickel silver ferrules Solid nickel silver slides inside and out (amazon description). Sells brand new for 4 dollars. I am taking into consideration it will need some scratches buffed out and general maintenance somewhere like Reimans because it has not been played for 10 years. It was bought in 2000 and only used for about 4 years and well cared for.
