Antique late 1800's dolphin koi sauce boat French white opal glass

Antique late 1800's early 1900's dolphin koi sauce boat French white opal glass i believe this is French white opal glass because it is slightly translucent which milk glass is solid opaque white glass. Either way it stunning unique & a definite fun conversation started at any dinner table. I just love his happy little face! the lid has a small chip on the underside towards the back. it is hardly noticeable & not indanger of breaking further. it has been filed and there are no sharp edges or stress fractures/ cracks. see picks! approx measurements 7" L 3"W 2.25" H w/o lid 4.5" H with lid antique, vintage, opalescent or milk glass, dolphin, koi, gravy, relish, sauce, holiday, formal kitsch
