goodness - I can't even spell 'than'...

Have just listened to Martin Carthy's 'Jack Orion' (a version of Glenkindie) Toward the start of the song, someone twirls at the pin. Later a different character 'twirls at the ring' Given my limited knowledge of bell-pull over that last few hundred years, this seems more reasonable. Is a 'pin' simply a synonym for a 'ring?'
