I am not sure if I have titled this item correctly, please help me out and let me know if you have more info about this item.

This tachometer will fit many CB750's from the early 1970s.  It is in fairly good used condition with a few small blemishes on the housing and lens, including a scratch along the outer edge of the housing that is about an inch long.  This auction includes the back cover.
