This is a before and after picture of an older Holton ST550 trumpet from my inventory that I think is from the late 1970’s or 80’s. They were billed as intermediate horns, but play as well as a pro horn. When I first pulled it out of the case it was a little beat up. A little dent work later and I think it turned out pretty well. My wife played this one, and it sounded as good as her Benge trumpet. Now it looks as good as it sounds!
