• Please find a refurbished by seller Selmer 1948 Grands Prix 20B medium large bore(pre K-Modified era) model Bb trumpet with a 1st valve trigger and an excellent condition Yamaha double trumpet case offered. No mouthpiece is offered but please inquire as to your requested brand/model I may have your selection.  The bore size measured on the 2nd valve slide measures .456"(medium large bore). The bell diameter measures 4.75".  The serial number is 7284 produced by Selmer in Paris, France in 1948. 
•  All dings were gently removed paying  close attention to preserve all etchings, serial number etc.. The horn was then re-lacquered utilizing a baked on epoxy lacquer. The satin lacquer finish is not perfect but close, no lacquer runs. Some slight signs of last step buffing swirls somewhat noticeable here and there please see pictures. The instrument has been chem cleaned and thoroughly cleaned inside and out. The horn was ultrasonically cleaned as well. All new valve stem corks and felts. Excellent port alignment. The 1st valve trigger and the 3rd valve finger ring adjustment move freely without drag. Excellent valve speed and compression.
• The horn will be thoroughly hand polished again the day before shipping. It will be clean, shiny, sanitized, valves oiled, slides lubricated and ready to play right out of the box. I will also include an "Ultra Pure Deluxe Trumpet Care Kit" with the shipped horn(see picture with case). In addition I will include a 4oz bottle of liquid Selmer Lacquer Polish that will aid in keeping the epoxy lacquer finish shining for years to come when used as needed. 
• Feel free to ask questions. Thanks for looking.
