Definately not an original Meucci bumper from the '70s. When Meucci changed to the newer style bumpers they made 2 sizes. Small and large hole for the old and new Qs, but both sizes have the new style head. If an original bumper is lost u must buy the new style bumper or leave an empty hole and an unprotected butt cap. The bumper in the pic has the new style head. In my collection I have several 70s-80s Qs with the new style bumper heads. It was/is very easy to lose the old style bumpers as were simply straight and frequently fell out. Even the new bumpers fall out too, but not as bad as the old ones.
