This is a 1991 Conn 79H in a lacquer finish. This instrument is here on consignment from John Mosca. The overall condition of this horn is fantastic. Slide feels great, and rotor moves freely. COuld fit into various different playing situations. The 79H is essentially the same as the 78H, except the 79H has the F rotor attachment while the 78H doesn't. It is a #3¾ bore (0.522"). Comes with case, and serial number is 41362797.
