i have a buescher aristocrat true tone trumpet that i played for roughly ten years. for many reasons, i stopped playing. so now i have this beautiful vintage trumpet sitting around. i believe this trumpet is well over 60 years old. the serial number is 320748. it was made in elkhart, IN before the factory burnt down and selmer bought buescher. it is gold plated with mother of pearl valve tops and engravings all over. who should i contact if i wanted to sell? and can anyone let me know more about this piece of history i have? thanks!
