THE SECOND SET HAS THE SMALL CUTTER THAT WAS MARKED AS 2ND OVER, CHANGED TO 4TH OVER, 2 OF THE THREE ARE MARKED SECOND OVER, ONE OF WHICH WAS NEVER UNSEALED, THE 3RD ONE WAS ORIGINALLY 2ND OVER, RE-SET AND MARKED 4TH OVER. THESE TWO CUTTER SETS WERE RARELY USED WHEN I WAS REMACHINING BEETLE ENGINES, AS BY THE TIME A CASE NEEDED TO BE BORED 4TH OVERSIZE, IT WAS USUALLY TOO FAR GONE TO RISK MY REPUTATION FOR BUILDING QUALITY ENGINES THE FIRST SET PICTURED IS STANDARD 4TH OVER, THE SILICONE ADJUSTER SEALING PLUGS HAVE NOT BEEN REMOVED TO CHANGE THE SETTING.
