This is a lovely gold tone metal Gentleman's watch chain. I think it is gold filled but it is not marked. It has BSF Co on the swivel. There is a lovely weighted fob with the initial G.N.H., this watch holder is 5 inches long with a 6 1/2 inch watch chain with swivel. The piece that clips over the vest pocket edge is covered with lovely gold work. Then there are 4 chains that attach to the pretty fob. To you from Kansas A Gentleman's watch holder.
