I bought this from a Chinese gentleman who sells Asian pieces he ships to Europe from China to sell at auctions. He was doing a fund raiser for the boosters club on the Naples Navy Base in Naples, Italy. I believe it is original and not a reproduction. It is made of wood and brass and the seat looks like things i've seen made from horsehair rope. It folds up to be more portable. He described it as a field marshal's chair used in battle to make the commander comfortable.
As the picture shows there is a crack in the wood on the back. There are no markings.
