Travel chess set with metal chessboard box

A landmark of the 19th century industrial revolution, today, this metal box can hardly be called a travel set: it is bulky, very heavy for its size and impossible to put in a travel bag, not to mention a pocket. However, it did apparently boast the first-ever magnetic pieces, which did not slip off the board in jolting trains or on rocking transatlantic steamers. And, for safety purposes, the box has lockable sliding drawers for chess pieces, finished with red cloth on the inside.
