This is going way back to 50's and 60's, and it was a poor practice even then! On cheap rebuilds some shops would save and reuse old pistons and sloppy bores by knurling the skirts. They then fitted oversized rings and filed the end gaps to fit the worn cylinders.
Unfortunately this was a temporary fix, as the knurling on the skirts quickly wore, resulting in piston slop and the newly refreshed engine smoking quickly.
