The mounting attachment also includes a pivot connection for permitting selective tilting of the magnifying element about a pivot axis extending generally parallel to the longitudinal axis of the scale. The mounting attachment further permits manual shifting of the magnifier in directions generally paralleling the longitudinal axis of the scale.
