I do not know much about trumpets and have not tested how it sounds (I do not play the trumpet). The serial number is hard to see, but it looks like it ends in 4750. It does have dings/scratches/wear… One of the valves gets stuck. Everything does slide apart. Comes with hard case… Still in tact, but it has discoloration and chipping off the edges. Comes with Vincent Bach Mouth Piece. The item “VINTAGE C. G. CONN LTD ELKHART IND. TRUMPET and CASE MOUTH PIECE RESTORATION/PARTS” is in sale since Wednesday, April 3, 2019.
