King Trombonium Vintage 1970's

King Trombonium from the 1970's.  Is a Bb 3 valve horn.  Very similar to the valve trombone, but plays much more open.  These have been around since the late 1930's.  This may have been the very last instrument model designed by White prior to his departure.  Has 8" bell and is .500 bore, takes standard small shank trombone mouthpiece.  Ideal size for a young player starting out.  Is lightweight and easy to handle.  Has been chem cleaned and adjusted, new felts, pads, springs.  Lacquer is not perfect but still has good appearance and is totally playable.  Does not have a case.  These have been seen recently on Ebay for $995-$2100.
