I was the only one of our five, two brothers, and two sisters, who escaped this, so I got to see plenty of shows-we had no telly up there until around 1960!
Oh, and shows it usually once the naughty ones were pinned in place, mostly over the knee, or piano stool if wee ones, it was breeks, skirts, shorts, and 6-8 smacks or spanks.
The bared bottom was usually reserved for street spankings. This was to make a real example of a real miscreant or persistent pain in the backside.
And that was sometimes done by the local polis-PCs for girls, WPCs for boys, especially if there was vandalism or nicking from shops involved. The Bobbies often wore leather gloves. They needed nothing else like a belt-12 smacks that I saw given must have been like those old army floggings in 1803-500 lashes-loud, public & pretty painful.
