A number of years ago, in my early youthful playing days I was given a lacquered Bach 42 Tenor trombone (straight) by a family member. I now don't these days play it too often, generally sticking to my Conn 88H. However, I recently used it and looked to find out a bit more about it. I can find quite a bit of information about the 42B (the triggered version) but not too much about the 42. I wondered whether anyone on here might be able to help - in particular what kind of value it might have?
