ABSTRACT:
A last event indicator apparatus includes a cylindrical support having a longitudinal axis, an outer surface and a tapered flange structure. The tapered flange structure has a first end having a first diameter and a second end having a second diameter that is greater than the first diameter of the first end. An expandable indicator ring is disposed over the outer surface. The indicator ring is axially displaceable along the longitudinal axis to engage the tapered flange structure and cause expansion of the indicator ring. The expandable indicator ring is rotatable about the longitudinal axis over the outer surface to each of a plurality of selected positions.
