E. Benge Trumpet Resno Tempered Bell, 3 ML USA.  Serial #980848.  Purchased new in 1985 and then I traded the owner (my trumpet instructor) for this horn.  It is a very solid horn with great compression.  My instructor never pulled out the valves to oil them, nor did I.  The valves work great and are in excellent shape including new pads.  He and I both played lead on this horn and it has a great rounded, bright, centered sound. I think it's a great jazz horn. It has not been played much the last twenty years because life and kids happened.  Recently it was professionally ultra-sound cleaned and refurbished.  There are no major dings on the horn. All slides and valves work great.  The case is a little beat-up, but still functional.
