Our son played this in 2007-2009 during sixth and seventh grade. 1st chair!
It was rented and then purchased by us through Quinlan & Fabish. It is a Jupiter cornet model JCR _520 M. After he stopped playing we had it serviced by Ellman's music center in Naperville.
We have a certificate stating "this instrument has been properly cleaned, sanitized and is good playing condition"
Comes with a cleaning kit, valve oil, slide grease and a straight mute
