What is this a coal fire starter/bellows or?
This looks like it could be for starting a fire with coal. The metal can has a hinged top and an open spout. Inside is a grate a couple of inches from the bottom. It is attached to a bellows made of wood and possibly leather. There is a hole in the bottom of the bellows that blows the air into the bottom of the can under the grate.
