Here we have a classic example of a medium large bore Bb/F closed wrap tenor trombone. The slide is slick with no signs of wear on the inner legs. The serial number 89462 means it is not of recent build so the lacquer is in the condition that you would expect from a older Bach with wear throughout however there is no signs of red rot. It has been chem cleaned, serviced and the valve action is spot on. The upper register on this instrument is to die for with a cracking tone throughout.
