I have to harken back about forty years for this so I can't say it is accurate. The overhaul manual for a specific engine will show the limits of bore out on a cylinder. On large radial engines they required that a colored band be painted on the cylinder just above the bottom flange that the retention bolts pass through. If I remember correctly if a cylinder had an orange band on it the cylinder would be scrapped at the next overhaul or if that specific cylinder had to be changed. It was not uncommon on larger engines (1830/1820 and 2000/2800) to see cylinders with different colored bands and some cylinders with no colored band which indicated it was new.
