Dark blue with white bird and vine pitcher

Small 7inch decorative pitcher.  Dark blue pebbled-appearing background with 3-dimensional vines, probably grape leaves and berries or grapes swirled all over pitcher.  The vines originate from the top of the handle, the handle appears to be 4 main vines that attach to the body of the pitcher - where the vines swirl out onto the body of the pitcher and become leafed.  There are 2 birds in the same white 3-D motif, one on each side, both standing on a vie - one with a long neck and long legs and the other with a shorter neck.  they are eating the berries/grapes.   There is a raised diamond shape with a big R in the center - an S at the top a 2 at the bottom and maybe a 17 at the side. There is a little circle at the top of the diamond with IV in it and there is 187 etched into the bottom of the piece.
