This is American Pneumatic Tool part number 1280179533, which replaced the older number 19433 T-Handle – bare, stocked at Crowder Supply as APT19433. This is what the operator holds. Handle components on a rivet buster absorb vibration and get dropped, so they wear out on calendar time rather than run hours.
You will find it on the diagram for the 133CN T-Handle Rivet Buster and 1133CN T-Handle Rivet Buster. It comes off the APT 133 Pneumatic Rivet Buster.
Everything else on that machine is one page away, and the parts diagram library indexes every breakdown we publish. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
