I'm selling this vintage Conn Constellation trumpet.

　　I know nothing about it, I picked up through storage unit auctions. It appears to be in good shape. It does make sound, that's all I know.  Appears to be mainly silver with brass pieces.Pics are accurate. I believe the case might be the original.

　　Serial number is pictured if that helps to identify better.

　　If you have any questions I'll try to answer to the best of my ability.

　　Thanks for looking.

　　Bell is 5".
