I have a Trumpet that my aunt gave to me in 1995, I dont know whe it was made. What I do know is, it's a King UMI with serial numers that read like this : 39 260937 It has a few minor scratches that I'm sure can be buffed out, it works well, and I have the case. I was curious as to how much it may be worth? Anyone that could help, I sure would appreciate! Thanks!
