Ordering by number: this is 1280179537, which replaced the older number 19438, the American Pneumatic Tool spring. It supplies the return force for its assembly in the rivet buster. A spring that has taken a set gives soft or sticky action long before it actually breaks.
You will find it on the diagram for the 133CN T-Handle Rivet Buster and 1133CN T-Handle Rivet Buster. That machine is the APT 133 Pneumatic Rivet Buster if you are pricing a replacement rather than a repair.
