Hey all, I have a question for the historical experts of the forums.. Does ANYONE know anything about the "American Diplomat" company? It is, to date, the ONLY entity that I would think should be widely known that is completely absent from the internet. Nowhere online is there ANY information on this company. I have one of their trumpets and was wondering about value, dating, etc. The trumpet is in very good condition with some small cosmetic issues - minor wear and tear that could most certainly be polished out with only one small ding that I can see. "American Diplomat" is stamped into the bell of the trumpet and it bears the serial number 20789. Thanks for your input, everyone.
