For your consideration is this Holton Al Hirt special trumpet. I don't know anything about trumpets but I will do my best . I believe it is a T-500 model although I cannot find the model mark.. The serial number is 421241. The mouthpiece is marked Getzen Co Elkhorn Wis. and is 3 3/8" long. The trumpet has three valves and one of them goes down slowly. Must have to be lubricated. There are a couple of small dents and some wear. The case is not in great condition but is usable. I have taken a lot of pictures so you be the judge. It came from an estate in upstate N.Y. so I am selling it AS IS and no returns. It weighs 12 pounds packed. Thanks for viewing and please see pictures.
