Ordering by number: this is 1280583539, listed as 03571 before the renumbering, the American Pneumatic Tool cylinder. The cylinder is the bore the piston runs in, and it sets the working clearance of the breaker once the bore opens up, air bypasses the piston and blow energy drops.
It appears on the 117 Paving Breaker and 118 Clay Digger, and on 1 other machine breakdown. That machine is the APT 117 Pneumatic Paving Breaker if you are pricing a replacement rather than a repair. Check it against the reference number on the diagram first; serial breaks change what fits.
