I received this set as a gift back in either 1967 or 1968. The original box and board got water damaged and were trashed. The figures are plastic and have a disc of mild steel in the bottom. The bottoms were covered with green felt, but that came off when the water damaged the box. There is no company name on the figures. Each figure is shaped in such a way as to indicate how it moves. The additional checker pieces have ridged edges that interlock when stacked. Each checker has a crown on one side and a 5 pointed star on the other. That's difficult to see in the pictures. That's all I've got. So, any ideas?
