In a German catalogue for flatware and hollowware (SMF Wellner SÃ¶hne, XXXV ed. 1914) is shown a butter cooler with a hook, for hinge up there during use the tap of the bowl.

In Â»925-1000Â« is appraised a Â»MeridenÂ« catalogue from 4th quarter of 19 century - only visible for North Americans and invisible for Europeans. At least the whole "e-book" range is totally invisible in Portugal.
It seems to me, that for similarity of Â»Meriden'sÂ« market (US), some one of the American readers should search in American internet archives for old catalogues of hollowware articles from 4th quarter of 19 century as well. There must be - for sure! - a visible solution for this question.
