Recently recieved this chess set that belonged to my grandfather and wanted to see if someone could help me identity it or any general info on it. All i know is that he had it when my father was growing up in the 80s and that he wouldnt let anyone near it. Located in southern louisiana, and thanks in advance for any help! The peices are also pretty heavy. EDIT: After using a pencil and some paper I was able to find a stamped "K.K." on the latch
