This listing features a very nice vintage, King Master Cornet, made by the HN White Company, Cleveland, Ohio.  It is ready to play.  The cornet is marked as "medium bore", and has serial number 269724, which dates it to approximately 1945.  

The cornet is in excellent condition.  I acquired it from a music store in Maryland that was going out of business.  I had the cornet professionally tested and repaired to place it in normal playing condition, including removing all dents in the bell and in tubing, and replacing the spit valve corks.    The valves and slides work well.   It was additionally tested and played in a community band rehearsal for one hour by an experienced player and was judged to be in great playing condition. 

See the "seller's notes" and photos for more condition details.

This instrument includes a King case, in very nice used vintage condition, including key for the locks.  The listing also includes a very nice Vincent Bach, Mt. Vernon, NY, 7C Cornet mouthpiece.
