Ordering by number: this is 1280583107, which replaced the older number 03158, the American Pneumatic Tool front valve chest. This part controls the working cycle of the rivet buster. When its faces wear, the tool sounds different and the blow rate falls off usually the first thing checked on a slow machine.
It shows up in the parts breakdown for the 133-T/1133-T Rivet Buster and 133-ST/1133-ST Rivet Buster, and on 6 other machines. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
