A wooden handle that old is going to have 2 rivets, most of the ones I've come across that are in bad shape are better off replacing with a new handle. You'll have to drill a hole in the center of the bracket. A single screw wood handle won't work because the bracket does not have tabs to secure the handle and it will eventually spin around the bracket.(been there, tried that) In the long run a new handle is the way to go.
