OEM tachometer taken from a 1973 Honda CB750K.  Will fit 1972-1978 but the face is period correct for 1972-1975. The 1972 U.S. Models used 2 mounting methods. Early models used a band type mounting.  Later 1972 and all subsequent models used a 2 bolt mounting.  If purchasing for a 1972 check for mounting before purchasing. The chrome housing is dented as shown in the pictures.  Otherwise this unit is in very good condition. Good working condition
