Hello All. I believe I have narrowed this down to Portugal, Porto, 833/1000, 1886-1938. But I can't figure out the 2nd mark. I did see similar pieces by D. Joao V, but never a pic of his maker's mark. Any help is appreciated. 13 inches Diameter, 14.5 oz. Thanks. https://www.925-1000.com/pics/Ximg.jp...
