A new comment on an old post says:
I have run across the occupation “pail turner” I can’t find this on any lists of obsolete occupations so I’m hoping you might either know the answer or have an idea where I might look.
Sure enough, if you google the phrase you get a number of old census records resembling “Newcomb Lewis 23 M Pail Turner NH” and lists of occupations like “151 Packer 2. 152 Pail turner 1. 153 Paint store 2,” but no explanation of what a pail turner does (or rather did). Anybody know?
