I ran across the opportunity to buy an old York trumpet. Can anyone share some info on these? Any good? Comparable to...? What are the model names in from bottom to tops? The one I was looking at seemed to be fairly thick and heavy metal -the spit valves resemled an Olds Ambassador. It was missing a right hand finger hook (broken). No dinks but lacquer about gone. Worth making an offer on it? Didn't have a mouthpiece with me. Thanks in advance.
