Renaissance chess set with rooks as castles on elephants

I had a set like this, given to me by my father in or around 1960. I burned in a fire that destroyed my home. All the "renaissance" sets that I see now on eBay are the Lloyds light-weiht plastic with a narrow castle tower for the rook. The set I had was rather heavy plastic material, with the King about 5-1/2 inches tall or more. Thanks
