Went to a home sale & picked up a very strange shaped vase, 8 1/2" height, 6" diameter, gold & silver enameling, cased. I don't have a clue but am guessing Czech/Bohemian. Vase was filthy dirty & enameling was hardly visible. Roman Numeral? III in bottom. Rim ground flat with gold. Any input very much appreciated on this one as I am clueless. Thanks, Ken
