I have estimated the date base on-line research. Please consult your expert. This vessel is in exceptional condition. It was made by Royal Worcester and has the mark and #1048, an "x" and Rn 21627. I believe these are museum quality pieces.The size is 3.8" x 3.7".
See my other listing for another Royal Worcester piece which is a double spouted pitcher which is a match of one in the Metropolitan Museum of Art.
