Just speculation. Perhaps that regulator was custom made or fit to order at the factory to avoid scrapping a block.

There is one SC mention for 21st series where dealers were notified because of material shortages some engines were shipping with .020 oversize pistons to avoid having to scrap the blocks. A star after the motor number was the indication of that non standard item.

Maybe some of the oil passages also had problems with clean up in the area for the regulator and had to go slightly oversize. You just happened to get a used item from one of those engines.

IIRC, for the same reason there were some Ultramatics with oversized valves for the 52 or 53 year and a special designation at the motor number.
