This is for a buddy of mine. We know they are not U.S. however marked Czech pieces with this Cambridge Azurite color have been found, so perhaps they are Czech. These were made in two parts, both press-molded and the upper parts hand-worked and joined to the bases. The broken pontil marks on the bottoms were crudely smoothed with an engraving/dremel-like tool. They are 7-7/8" tall. Any ideas/input sincerely appreciated. Thanks, Ken
