yes, agree, very delightful little piece

Not that it will help with finding the maker, but some idea of size will be of interest, please.
I've just ploughed through Gulliver but nothing that matches this piece, though he does show a few salts from the last ten to twenty years of the C19 - with typical pincered decorated feet and shaped like yours, plus knobbly bits, though all but one are unattributed and the one he does name has a French origin and looks nothing like yours.
Walsh Registered acres of flamboyant designs in typical OTT Victorian glass c. 1851 - 1914, but don't know that they made any salts, and the S. & W. book (R. S. Williams-Thomas) is way too brief to help with things like this.
By their nature, salts were mostly just small undecorated and plain looking pieces of utilitarian glass, and it's very unusual to find an example with such artistic appeal as this one.
This piece has all the hallmarks suggesting late C19, but suppose it's not impossible that it might be from a later date - what if any is the extent of wear inside the bottom of the bowl, and do the feet show any indication of age?
Sorry this is unhelpful, hopefully others will have something more positive to suggest
