摘要: A last event indicator apparatus (20, 100, 150) includes a cylindrical support (22, 103, 152) having longitudinal axis (24), an outer surface (26, 112, 156) and tapered flange structure (28, 104, 157). The 157) has first end (30) diameter (32) second (36) that is greater than the (32). An expandable ring (40, 106) disposed over 156). axially displaceable along (24) to engage cause expansion of 106). rotatable about each plurality selected positions.
