Little Women/Good Wives

I've just learnt that Good Wives is a purely British way of referring to vol 2 of Little Women. I wonder though what accounts for the textual differences between GW and vol 2 of the two-volume version?

So for example, in the opening scene of the one-volume Little Women, Jo examines the heels of her boots in a gentlemanly manner while urging her sisters to spend their money as they wish, whereas in the two-volume version, it's the heels of her shoes.

Susie Brann's Harpoon voice

Listening to the 1962 Carleton Hobbs adaptation of Thor Bridge, I find one Beryl Calder playing Grace Dunbar, with a voice that's uncannily similar to the posh 30s one Susie Brann deploys in The Harpoon. I wonder if that's where the latter modelled it from?
