Pair of Copper and Brass Display Stands DP34

Original, quality pair of circa 1900, heavy circular brass and copper display stands. This pair of circular tubs with a copper cylindrical body and heavy brass bases and top rims. The copper has dovetailed joints and is of the highest quality. No makers' or owners' mark can be seen and all now has been polished and lacquered, although the lacquer may be removed at no extra cost. Have you any ideas as to its purpose? In good order.
